Feet to Meters Conversion — Complete Guide for 2026
Converting feet to meters is one of the most frequent imperial-to-metric conversion tasks encountered in international construction, real estate, engineering, athletics, and everyday life. Whenever a U.S. measurement — a ceiling height, a room dimension, a building height restriction, or an athletic distance — needs to be expressed in the metric system used by the rest of the world, the calculation rests on one exact, internationally defined relationship: 1 foot = 0.3048 meters exactly. Multiplying your foot value by 0.3048 gives you a result derived from a mathematically precise constant, not an approximation.
Our free Feet to Meters Converter performs this calculation with up to 8 decimal places and automatically outputs results across the full unit ladder — meters, centimeters, millimeters, kilometers, yards, inches, miles, and nautical miles — alongside a live logarithmic bar chart and a downloadable 2-page PDF report formatted for professional documentation and project archives.

Why 1 Foot = 0.3048 Meters Exactly
The globally agreed, mathematically exact metric definition of the foot dates to July 1, 1959, when six nations — the United States, United Kingdom, Canada, Australia, New Zealand, and South Africa — signed the International Yard and Pound Agreement. The treaty defined the yard as exactly 0.9144 meters, making the foot exactly 0.3048 meters and the inch exactly 0.0254 meters (25.4 mm) — all to infinite decimal places, with zero rounding anywhere in the definition chain.
Before 1959, different countries maintained slightly different foot definitions. The U.S. survey foot was approximately 0.30480061 meters, while the British imperial foot aligned slightly differently. These divergences were invisible in everyday measurement but caused accumulating discrepancies in cross-border engineering projects, precision manufacturing catalogs, land survey records, and aerospace parts specifications that spanned national boundaries. The 1959 agreement eliminated all of it by anchoring the entire imperial unit system — foot, yard, mile, inch — to the meter through exact, terminating decimal relationships.
Why feet-to-meters is mathematically cleaner than the reverse
Unlike meters-to-feet (where the factor 3.280839895… is a repeating, non-terminating decimal), the foot-to-meter factor is 0.3048 — a perfectly terminating decimal. This means every whole foot value — 1 ft, 5 ft, 10 ft, 100 ft, 5280 ft — converts to an exactly terminating decimal in meters. There is no accumulated rounding from the conversion factor itself. For example, 10 ft = exactly 3.048 m; 5280 ft = exactly 1609.344 m (one statute mile). This mathematical cleanliness makes feet-to-meters conversions ideal for applications where exact termination matters — international specifications, contracts, and engineering drawings where rounding footnotes create ambiguity.
The calculator uses double-precision floating-point arithmetic (approximately 15 significant digits of accuracy), which is far more precise than any physical tape measure, laser distance tool, or digital calliper. At 4 decimal places, your result is accurate to within 0.00005 meters — about 0.05 mm — more than sufficient for any construction, engineering, or scientific application.
What the Feet to Meters Converter Calculates
Every output is derived from the same single multiplication — no intermediate rounding between units — giving you a complete metric and imperial breakdown from one instant calculation.
Decimal Meters (Hero Result)
The primary conversion multiplies your foot value by the exact international constant 0.3048. The displayed result is rounded only to your chosen precision — the underlying calculation uses full double-precision arithmetic. Decimal meters is the format used in international engineering drawings, metric building codes, manufacturer data sheets from non-U.S. suppliers, and scientific publications wherever SI units are required.
Centimeters & Millimeters (Summary Cards)
Centimeters (feet × 30.48) and millimeters (feet × 304.8) are the most common metric sub-units for construction and product specifications. A door that is 6 ft 8 in tall appears as 2.0320 m, 203.20 cm, and 2032.0 mm in metric — millimeters being the preferred unit in European construction drawings and Australian building codes. All three are shown simultaneously in the summary cards for immediate comparison without any extra steps.
Kilometers & Miles
Kilometers (feet × 0.0003048) and miles (feet ÷ 5280) provide the large-scale output needed for site plans, road distances, and geographic measurements. Because 1 mile = exactly 5280 ft = exactly 1609.344 m, the mile-to-kilometer conversion via this calculator is also mathematically exact — useful for running routes, road construction scopes, and zoning boundary descriptions that reference distances in both unit systems.
Yards, Inches & Nautical Miles
Yards (feet ÷ 3) appear in U.S. landscaping, fabric purchasing, and sports field dimensions. Total inches (feet × 12) is useful when a specification references inches only — pipe diameters, screen sizes, and appliance clearances. Nautical miles (meters ÷ 1852) serve maritime navigation, aviation flight planning, and international shipping documentation. All four are derived directly from the foot input without any intermediate rounding.
Visual Bar Chart
A horizontal five-bar chart plots the numeric magnitude of your value across feet, meters, centimeters, millimeters, and yards in five distinct colors on a logarithmic scale. The log scale handles the enormous spread between unit magnitudes elegantly — a 10-foot input shows millimeters (3048) as a dramatically larger bar than meters (3.048) without breaking the visual layout. The chart captures cleanly into the PDF for presentations and project documentation.

Converting Human Heights: Feet and Inches to Meters
Height is one of the most common contexts for feet-to-meters conversion. People in the United States describe their height in feet and inches (e.g. 5′9″), while people in metric countries record height in centimeters (e.g. 175 cm) or meters (e.g. 1.75 m). The table below covers the full range of typical U.S. adult heights from 5′0″ to 6′3″ in 1-inch steps, with the precise meter and centimeter equivalent for each.
| Height | Meters | Centimeters |

Feet to Meters — Key Conversion Numbers
The Feet to Meters Converter Is Built For You If…
Whether you're a U.S. architect translating imperial drawings for international clients, an American relocating abroad who needs metric equivalents for everyday dimensions, or a real estate professional converting U.S. property listings for international buyers — this converter delivers an exact, documented result in seconds.
Architects, Engineers & Construction Professionals
Drawings, specifications & international deliveryU.S.-based architects, structural engineers, and project managers delivering work to international clients — or coordinating with metric-trained subcontractors — routinely need to translate imperial drawings into metric specifications. A structural drawing in feet that reaches a European fabricator must arrive in millimeters. A ceiling height specified at 9 feet must be confirmed as 2.7432 m in a permit submission for a Canadian or Australian project. Incorrect conversions create rework, failed inspections, and change-order disputes.
- Use millimeters output for European and Australian construction drawings (mm is the preferred metric construction unit)
- Use 3–4 decimal precision for structural layouts and dimensional specifications
- Cross-check the km output when scaling site-plan distances for international planning submissions
- Export the PDF to attach to RFI responses, transmittal records, and project audit packages
Americans Traveling or Relocating Abroad
Heights, room dimensions & everyday measurementAmericans living in or relocating to metric countries encounter meters everywhere — rental apartment listings, furniture dimensions, ceiling heights, clothing size charts, road signs, medical height records, and product data sheets. Converting familiar U.S. foot measurements into metric equivalents helps make sense of new environments and avoids costly mistakes when ordering furniture, booking accommodations, or describing dimensions to local tradespeople who think exclusively in centimeters and millimeters.
- Use 1–2 decimal precision for everyday apartment and room dimension estimates
- Bookmark 6 ft = 1.8288 m for quick personal height reference abroad
- Use the centimeters output for furniture and appliance shopping — European specs always use cm
- Use Quick Presets for the most common U.S. room dimensions: 8 ft, 9 ft, 10 ft ceilings; 5 ft, 6 ft widths
Real Estate Professionals & International Buyers
Property listings, floor plans & valuationsU.S. real estate professionals serving international buyers — and foreign nationals purchasing U.S. property — frequently encounter the feet-to-meters conversion challenge. American MLS listings describe square footage, ceiling heights, lot sizes, and room dimensions in feet. International buyers expect meters. A 10-foot ceiling listed in a luxury condo becomes 3.048 m. A 50-foot lot width is 15.24 m. Accurate, documented conversion builds client confidence and avoids misunderstandings at closing.
- Use 2–3 decimal precision for real estate listing conversions — sufficient for property dimensions
- Use the PDF report to attach a formal conversion record to international listing packages and contracts
- Convert ceiling heights, room widths, and lot dimensions simultaneously using multiple preset inputs
- Use the centimeters output when corresponding with European buyers who use cm for room specifications
7 Tips for Accurate Feet to Meters Conversions
Multiplying by 0.3048 is simple, but a few professional habits prevent the errors that surface when imperial U.S. dimensions meet metric international specifications on the same project.
Always Use 0.3048 — Never 0.305 or 0.30
Using 0.305 instead of 0.3048 introduces a 0.066% error — about 0.66 mm per foot. On a 10-foot ceiling, that is 6.6 mm; on a 100-foot building span, it is 66 mm — nearly 3 inches. Using 0.30 is even worse: a 2% error that accumulates to 60 mm per 10 feet. The exact factor is 0.3048 — always. Round the result to your needed precision; never round the conversion factor itself.
Convert Feet and Inches Correctly
A common error is converting feet and inches separately as if both are feet. 5′9″ is NOT 5.9 feet — it is 5 feet plus 9 inches, or 5 + (9 ÷ 12) = 5.75 feet. The correct meter value is 5.75 × 0.3048 = 1.7526 m, not 5.9 × 0.3048 = 1.7983 m. The difference is nearly 46 mm — more than enough to cause fit failures in construction assemblies. Always convert feet-and-inches to decimal feet or total inches before multiplying.
Memorize These Five Exact Anchors
A small set of anchors covers most professional estimation: 1 ft = 0.3048 m, 3 ft = 0.9144 m (exactly 1 yard), 10 ft = 3.048 m exactly, 100 ft = 30.48 m exactly, 5280 ft = 1609.344 m (exactly 1 mile). Every anchor is an exact, terminating decimal. Knowing these lets you instantly sanity-check any result — if 8 feet comes back as 0.244 m, you know immediately it is wrong (should be 2.4384 m). The exact 10 ft = 3.048 m anchor is particularly useful for room and building height estimates.
Match Precision to the Application
0–1 decimal places for signage and public communication; 2 for real estate listings and product descriptions; 3–4 for architectural and construction drawings; 6–8 for surveying, scientific research, and precision engineering. Selecting higher precision than needed is harmless — selecting too low can cause rounding differences that matter in tight clearances, multi-step calculations that chain conversions, or contract specifications where fractions count.
Note That U.S. Building Dimensions Are Often Nominal
U.S. building dimensions frequently use nominal (round-number) values that differ from actual measured dimensions. An “8-foot ceiling” may be 7 ft 11.5 in to the finished surface. A “2-by-4” lumber stud is actually 1.5 in × 3.5 in. A “standard 6-foot 8-inch door” may be 80 in exactly, or 79.75 in actual. Always convert the measured dimension — not the nominal label — when checking international clearances, writing metric specs, or cross-referencing against metric manufacturer data.
Use Millimeters for Metric Construction Documents
In European, Australian, and most international metric building codes and construction drawings, millimeters — not meters or centimeters — are the standard unit for all dimensions below about 10 m. A door specified at 7 ft is expressed as 2133.6 mm, not 2.1336 m, on a metric architectural drawing. The millimeters output in this calculator provides that value directly. Understanding this convention prevents confusion when reviewing international drawings or corresponding with metric-country contractors and fabricators.
Use the PDF as a Permanent Conversion Record
For professional deliverables — international construction packages, supplier metric specifications, real estate contracts with foreign buyers, engineering submittals, or permit applications requiring metric documentation — download the PDF conversion report and attach it to your project file. It records the exact input in feet, all converted outputs, the international conversion standard used, and the generation date. If a dimension is ever questioned during inspection, contract review, or cross-border dispute, you have a timestamped record showing the conversion was performed correctly.
Feet to Meters Converter — Frequently Asked Questions
Everything you need to know about converting feet to meters, the history of the 0.3048-meter foot definition, how to handle feet-and-inches inputs, and how to apply this calculator accurately across construction, real estate, travel, and everyday projects.
To convert feet to meters, multiply the foot value by 0.3048. The formula is: meters = feet × 0.3048. For example, 10 feet × 0.3048 = 3.048 meters exactly.
For feet-and-inches inputs, first convert to total inches (feet × 12 + remaining inches), then multiply by 0.0254 (since 1 inch = 0.0254 m exactly). Example: 5 ft 9 in = (5 × 12) + 9 = 69 inches × 0.0254 = 1.7526 meters. The calculator above performs all steps automatically with up to 8 decimal places and outputs every related unit simultaneously.
1 foot equals exactly 0.3048 meters — this is a defined constant, not a rounded approximation. Equivalently: 1 foot = 30.48 centimeters = 304.8 millimeters = 0.0003048 kilometers.
Key anchors: 3 ft = 0.9144 m (exactly 1 yard) · 10 ft = 3.048 m exactly · 100 ft = 30.48 m exactly · 5280 ft = 1609.344 m (exactly 1 mile). Because 0.3048 is a terminating decimal, every whole-foot value converts to an exactly terminating decimal in meters — a mathematical advantage over converting in the reverse direction.
The exact formula is: meters = feet × 0.3048. This is mathematically exact — 0.3048 is a defined constant, not a rounded number. To reverse: feet = meters ÷ 0.3048, which equals meters × 3.280839895… (a repeating decimal).
Quick anchors: 1 ft = 0.3048 m · 3 ft = 0.9144 m · 10 ft = 3.048 m · 100 ft = 30.48 m · 5280 ft = 1609.344 m. Because 0.3048 is a terminating decimal, every foot value converts to an exactly terminating decimal in meters — no rounding from the factor itself, only from your chosen display precision.
The exact 0.3048-meter definition of the foot was established by the International Yard and Pound Agreement of 1959. Six nations — the United States, United Kingdom, Canada, Australia, New Zealand, and South Africa — agreed to define the yard as exactly 0.9144 meters, making the foot exactly 0.3048 meters and the inch exactly 0.0254 meters (25.4 mm) — all to infinite decimal places, with no rounding anywhere in the definition chain.
Before 1959, the U.S. survey foot was approximately 0.30480061 meters, creating measurable discrepancies in cross-border engineering projects, precision manufacturing, and land survey records. The 1959 agreement eliminated all of it. NIST officially retired the U.S. survey foot effective January 1, 2023 — completing the global transition to one universal standard: 1 foot = 0.3048 meters, everywhere.
5 feet equals exactly 1.524 meters, or 152.4 centimeters, or 1524 millimeters. The calculation: 5 × 0.3048 = 1.524 m — an exact, terminating decimal result with no rounding.
5 feet appears in many practical contexts: the minimum height for many amusement park rides and sports participation guidelines, a common hallway clearance minimum in building codes, and a standard vanity or counter height reference in residential design. In metric countries, a 1.524 m (152.4 cm) measurement is common in women's clothing size charts and pediatric height references for children approaching typical adult height.
6 feet equals exactly 1.8288 meters, or 182.88 centimeters. The calculation: 6 × 0.3048 = 1.8288 m — exact and terminating.
6 feet is one of the most culturally significant height references in the U.S. — widely perceived as the threshold for “tall” in everyday conversation. In construction, 6 feet (1.8288 m) is the standard height of a residential privacy fence and the minimum clearance in many low-ceiling applications. In metric countries, a person described as 6 feet tall is recorded as 182.88 cm — or rounded to 183 cm — on medical forms, sports registrations, and passport records. Use the Quick Preset chip in the calculator above for the instant full breakdown.
100 feet equals exactly 30.48 meters, or 3048 centimeters. The calculation: 100 × 0.3048 = 30.48 m — exact and terminating.
100 feet is a key planning and regulatory reference: the maximum height for low-rise zoning in many U.S. cities (approximately 9–10 stories at standard floor heights), a common FAA drone operation altitude limit, and a round-number building height used in construction estimating. In international athletic contexts, 30.48 m is the metric equivalent of a 100-foot throw or jump distance — useful for comparing U.S. imperial sports records against metric world records.
To convert feet and inches to meters manually, use either of two equivalent methods. Method 1: Convert to total inches first (feet × 12 + remaining inches), then multiply by 0.0254. Method 2: Convert feet and inches separately and add — (feet × 0.3048) + (inches × 0.0254).
Example: 5 ft 10 in. Method 1: (5 × 12) + 10 = 70 inches × 0.0254 = 1.778 meters exactly. Method 2: (5 × 0.3048) + (10 × 0.0254) = 1.524 + 0.254 = 1.778 m. Both methods produce the identical result because they are mathematically equivalent. The height reference table on this page pre-computes this for heights from 5′0″ to 6′3″. For the calculator, enter the decimal foot value (e.g. 5.833 for 5′10″) to use the full precision output.
5280 feet equals exactly 1609.344 meters, or 1.609344 kilometers. The calculation: 5280 × 0.3048 = 1609.344 m — an exact, terminating decimal with no rounding anywhere.
5280 feet is the definition of one statute mile. The metric equivalent is exact because both the mile-to-foot factor (5280 ft/mi) and the foot-to-meter factor (0.3048 m/ft) are defined constants with no rounding. This is why international road-race distances — 5 km (3.107 mi), 10 km (6.214 mi), the marathon at 42.195 km (26.219 mi) — are defined in meters, not miles: the metric values are the primary standards, and their mile equivalents are derived approximations. Use the “1 mile” Quick Preset chip in the calculator for the instant full breakdown.
The foot is an imperial unit of length used primarily in the United States — and informally in some contexts in the United Kingdom and Canada. The meter is the SI (International System of Units) base unit of length, used as the global standard in science, engineering, construction, education, and everyday measurement across most countries worldwide.
One meter equals 3.28084 feet, so the meter is a larger unit — a typical U.S. room of 12 feet across is 3.6576 meters, which is a smaller number but the same physical distance. When converting from feet to meters, your result will always be a smaller number: a 10-foot ceiling becomes 3.048 meters. Neither unit is more accurate; the conversion between them is exact in both directions. The principal practical difference is context: feet for U.S. domestic use, meters for international communication, science, and metric-country applications.
The calculator uses the exact relationship 1 foot = 0.3048 meters with double-precision floating-point arithmetic, accurate to approximately 15 significant digits. The display rounds only to your chosen decimal precision — the underlying calculation always uses full accuracy.
Because the conversion factor 0.3048 is a terminating decimal, the feet-to-meters conversion introduces no rounding error from the factor itself — only the display precision you select. At 4 decimal places, your result is accurate to 0.00005 meters — about 0.05 mm — far beyond any tape measure or laser distance tool. The downloadable PDF records your chosen precision, all output values, and the conversion standard, creating a complete auditable record of the conversion for professional documentation purposes.
Accuracy note: The HomeExpertly Feet to Meters Converter uses the exact international conversion relationship of 1 foot = 0.3048 meters, as established by the 1959 International Yard and Pound Agreement and currently recognized by the U.S. National Institute of Standards and Technology (NIST) and the International Bureau of Weights and Measures (BIPM). All calculations are mathematically precise to the decimal precision you select (up to 8 places). Because the conversion factor 0.3048 is a terminating decimal, every whole foot value converts to a mathematically exact, terminating decimal in meters with no rounding from the factor itself; displayed values are rounded only at the display step. Results are for informational and reference purposes only. For applications where measurement accuracy is critical — including but not limited to structural engineering, land surveying, medical height records, legally binding contracts, building permits, international product certifications, or scientific publication — always verify your conversions independently and use calibrated measurement instruments. Display rounding at lower precision settings (0–2 decimal places) introduces differences from the mathematically exact result that may matter in tight-tolerance applications. Nominal U.S. building dimensions may differ from actual measured dimensions; always verify on site or with calibrated instruments before converting. HomeExpertly is not responsible for any consequences arising from the use of these conversions, including mis-sized components, failed inspections, specification mismatches, contract disputes, or project rework. When in doubt, measure the actual dimension, use the highest available precision, and consult a licensed professional for measurement-critical applications.
