Feet to Centimeters Conversion — Complete Guide for 2026
Converting feet to centimeters is one of the most searched height and length conversions in the world — needed whenever a U.S. or U.K. measurement in feet needs to be expressed in the metric system used by the majority of countries globally. Whether it is a person’s height for an international medical form, a room dimension for a European furniture order, or an athlete’s stats for a global audience, the conversion rests on one exact, internationally defined relationship: 1 foot = 30.48 centimeters exactly.
Our free Feet to Centimeters Converter performs this calculation with up to 8 decimal places and automatically outputs results across the full unit ladder — centimeters, meters, total inches, millimeters, yards, kilometers, and miles — alongside a composite feet-and-inches breakdown, a live log-scale bar chart, and a downloadable 2-page PDF report. Because feet × 30.48 always produces a terminating decimal, this is the “clean” direction of the foot–centimeter conversion.

Why 1 Foot = 30.48 Centimeters Exactly
The foot’s metric equivalent was fixed on July 1, 1959, when the United States, United Kingdom, Canada, Australia, New Zealand, and South Africa signed the International Yard and Pound Agreement. That treaty defined 1 inch as exactly 2.54 centimeters. Since 1 foot contains exactly 12 inches, the chain resolves to: 1 foot = 12 × 2.54 = 30.48 cm exactly. No measurement was taken; the value is mathematically derived from the defined constant.
This makes feet-to-centimeters one of the cleanest unit conversions in everyday use. Because 30.48 is a terminating decimal, multiplying any foot value by it always yields a terminating (exact, finite) result in centimeters. There is no inherent rounding — 1 ft = 30.48 cm, 5 ft = 152.4 cm, 6 ft = 182.88 cm, and 10 ft = 304.8 cm are all mathematically exact. The displayed precision is purely a presentational choice.
Converting feet-and-inches to centimeters
When a height is given in mixed feet-and-inches format (e.g. “5 feet 9 inches”), two calculation approaches produce identical exact results. The first method converts each component independently: (feet × 30.48) + (inches × 2.54). Example: 5 ft 9 in = (5 × 30.48) + (9 × 2.54) = 152.4 + 22.86 = 175.26 cm. The second method converts to decimal feet first: 5 + 9/12 = 5.75 ft × 30.48 = 175.26 cm. Both paths give the same exact answer because 1 in = 2.54 cm and 1 in = (1/12) ft × 30.48 cm/ft = 2.54 cm — the same constant.
For the calculator, enter any mixed height as decimal feet. For example, 5 ft 7 in = 5 + (7 ÷ 12) = 5.5833… ft. The composite “Ft & In” output in the results panel reverifies your decimal input in the traditional mixed format — confirming you entered the right value.
What the Feet to Centimeters Converter Calculates
Every output is derived from the same single multiplication — no intermediate rounding between units — giving you a complete imperial and metric breakdown from one instant, exact calculation.
Centimeters (Hero Result)
The primary conversion multiplies your foot value by the exact constant 30.48 to produce centimeters. This is the format used in international medical records (WHO global growth standards, BMI databases, hospital intake forms), European furniture and interior dimensions, clothing size charts in metric countries, and any professional context where SI units are required. Because 30.48 terminates, 6 ft = 182.88 cm is exactly right — no rounding at all.
Meters
Meters (feet × 0.3048) provide the SI baseline unit for international scientific communication, architectural scale drawings, and engineering specifications. A room that is 10 feet tall is 3.048 meters exactly — a value that architects working across metric and imperial standards need immediately when scaling structural drawings. Meters also serve as a natural sanity-check: a 6 ft person should be around 1.8 m (1.8288 m exactly), not 18 m or 0.18 m.
Total Inches & Millimeters
Total inches (feet × 12, exact) expresses the measurement without the feet unit — useful for fabric widths, screen diagonals, pipe diameters, and U.S. clothing inseam tables. Millimeters (feet × 304.8, exact) give the highest-resolution metric output without scientific notation — essential for precision machining tolerances, woodworking joinery, print resolution, and engineering drawings where sub-millimeter accuracy must be documented. Both are exact multiplications of the same 30.48 constant.
Composite Ft & In Confirmation
The composite “ft & in” output reverifies your decimal feet input in the traditional mixed format. If you entered 5.75 ft, the composite display confirms “5 ft 9.0 in” — confirming the decimal-to-inches conversion is correct. This is especially useful when converting a height that was typed as decimal feet from memory: if you intended 5 ft 6 in (5.5 ft) but typed 5.6 ft, the composite output shows “5 ft 7.2 in” — immediately flagging the discrepancy before it reaches a medical record or sports profile.
Visual Bar Chart
A horizontal five-bar chart plots the numeric magnitude of your value across feet, centimeters, inches, yards, and meters in five distinct colors on a logarithmic scale. For a 6 ft input, centimeters (182.88) and inches (72) are both in the same order of magnitude, while yards (2) and meters (1.83) are much smaller — log scaling keeps all five bars readable and proportionally meaningful, with M/k suffixes on the axis to handle large architectural or structural dimensions cleanly.

Feet to Centimeters — Key Conversion Numbers
The Feet to Centimeters Converter Is Built For You If…
Whether you’re a healthcare provider entering a patient’s height into an international medical system, a sports analyst preparing a metric athlete profile, or a construction professional reconciling U.S. imperial drawings with metric specifications — this converter delivers an exact, documented result in seconds.
Healthcare & Medical Professionals
Patient records, BMI, clinical trials & international referralsU.S. patients and their medical records express height in feet and inches, while international medical systems, WHO growth standards, BMI calculators, and clinical research databases require centimeters. A clinician transferring a U.S. patient record to a European hospital needs the exact cm equivalent of “5 ft 11 in” for the receiving system’s intake form. Pharmaceutical dosing by body surface area also requires height in centimeters and weight in kilograms — making accurate foot-to-cm conversion a patient safety issue, not just a paperwork detail.
- Use 1–2 decimal places in cm for medical records — sub-centimeter precision is clinically adequate
- Use the composite ft & in output to double-check you entered the correct decimal feet value
- Use the full 5 ft 0 in to 6 ft 11 in reference table for rapid look-up without re-entering values
- Export PDF to attach to international referral packages, clinical trial data submissions, and insurance pre-authorization forms
Sports Analysts, Scouts & Media
Athlete profiles, draft boards & international broadcast graphicsU.S. leagues (NBA, NFL, MLB, NHL) list athlete heights in feet and inches. International sports media, European leagues, and global broadcast graphics require centimeters. A basketball analyst covering an NBA draft for a European audience needs to convert every prospect’s listed height to cm for on-screen graphics. A soccer club scouting a U.S. college player needs the cm equivalent of their listed height for the club’s metric database and transfer registration documents. Accurate, consistently formatted data is essential for professional credibility.
- Use 0–1 decimal places in cm for broadcast graphics and athlete profile cards
- Use the composite ft & in confirmation output to verify the decimal foot input is correct
- Cross-reference against the 5 ft 0 in to 6 ft 11 in look-up table for the most common athlete height range
- Export PDF to include in scouting reports, media guide production files, and official league registration forms
Architects, Engineers & Construction Professionals
Drawings, specifications, clearances & international projectsU.S. construction is specified in feet and inches. International construction — and increasingly, U.S. projects with international clients, suppliers, or subcontractors — requires metric dimensions. A ceiling height of 9 ft must be expressed as 274.32 cm for a European materials supplier’s order form. Door clearances of 6 ft 8 in (203.2 cm) must match the metric equivalent in a building permit submitted to an international client. Every rounding error in a structural dimension can cascade into material ordering mistakes and costly site corrections.
- Use 2–3 decimal places in cm for construction-grade precision — 1 decimal place in cm = ±0.5 mm
- Use the mm output for hardware specifications, joinery details, and machined component tolerances
- Use the 10 ft preset as a ceiling-height reference: 10 ft = 304.80 cm = 3.048 m exactly
- Export PDF to include in project handover packages, building permit submissions, and material order documentation
7 Tips for Accurate Feet to Centimeters Conversions
Multiplying by 30.48 is straightforward, but a few professional habits prevent the errors that arise when imperial heights and dimensions meet metric documentation, clinical records, and construction drawings.
Always Use 30.48 — Not 30 or 30.5
Using 30 introduces a 1.57% error — 1.57 cm per foot. For a 6 ft person, that is 9.43 cm of error — turning 182.88 cm into 180 cm. Using 30.5 introduces a 0.066% error (0.066 cm per foot), acceptable for casual estimates. For any professional output — medical records, sports databases, architectural drawings — always use the exact constant 30.48. The calculator does this automatically; the tip is relevant when computing mentally or in a spreadsheet without looking up the constant.
Convert Feet & Inches Correctly to Decimal Feet
The most common input error is treating inches as tenths of a foot. 5 ft 6 in is not 5.6 ft — it is 5 + (6/12) = 5.5 ft. Similarly, 6 ft 3 in is 6 + (3/12) = 6.25 ft, not 6.3 ft. A quick rule: divide the inches by 12 to get the decimal fraction. Verify your entry using the composite ft & in output in the results panel — if you entered 5.5 ft and the composite shows “5 ft 6.0 in”, the entry is correct. If it shows “5 ft 7.2 in”, you entered 5.6 ft by mistake.
Know Six Key Exact CM Values by Heart
For everyday use: 1 ft = 30.48 cm · 2 ft = 60.96 cm · 3 ft = 91.44 cm · 5 ft = 152.4 cm · 6 ft = 182.88 cm · 10 ft = 304.8 cm. All are exact. Knowing these lets you instantly bracket any result — 5 ft 9 in should fall between 152.4 cm (5 ft) and 182.88 cm (6 ft), nearer to the midpoint. If a result is outside that range, the input has an error. These anchors are also easy to verify: just multiply the foot value by 30.48.
Use Each Inch as a 2.54 cm Step
Because 1 inch = 2.54 cm exactly, every additional inch above a whole-foot height adds exactly 2.54 cm. This makes incremental height lookups fast: if you know 5 ft = 152.4 cm, then 5 ft 1 in = 154.94 cm, 5 ft 2 in = 157.48 cm, and so on — just add 2.54 cm per inch. The full reference table in this page’s height section applies this rule for every inch from 5 ft 0 in to 6 ft 11 in, eliminating the need to recalculate for each height increment.
Note That 183 cm ≠ Exactly 6 Feet
A common approximation in sports media and everyday conversation is “6 feet = 183 cm.” This is incorrect: exactly 6 feet = 182.88 cm. 183 cm is 0.12 cm more than exactly 6 feet. While this rounding is harmless in conversation, it matters in formal contexts: an athlete listed as 183 cm is not the same as an athlete listed as 6 ft (182.88 cm) — they are 1.2 mm different. For official registration forms, medical records, and legal documents, always use the exact 182.88 cm value, not the rounded 183 cm approximation.
Use the Millimeters Output for Engineering and Manufacturing
For precision engineering, machining, woodworking, and manufacturing specifications, millimeters (feet × 304.8, exact) provide the most useful metric output. 1 ft = 304.8 mm exactly; 6 ft = 1828.8 mm exactly. Millimeters avoid the decimal point handling of centimeters for sub-centimeter measurements and match the preferred unit of most engineering drawing standards (ISO 128, BS 8888, ASME Y14.5) outside the United States. The mm output in this calculator is exact for any whole or half foot value.
Use the PDF as a Permanent Dimensional Record
For professional deliverables — patient referral packages, athlete registration forms, building permit submissions, or manufacturing inspection records — download the PDF conversion report and attach it to the project file. It records the exact foot input, all converted outputs at your chosen precision, the conversion standard (1 ft = 30.48 cm, 1 in = 2.54 cm), the composite ft & in display, and the generation date. For any height or dimension measurement later questioned, the PDF provides a timestamped, auditable conversion record with no ambiguity about the source value or method.
Feet to Centimeters Converter — Frequently Asked Questions
Everything you need to know about converting feet to centimeters, entering mixed feet-and-inches values, the exact 30.48 constant, common height benchmarks, and how to apply this calculator accurately across healthcare, sports, construction, and everyday projects.
To convert feet to centimeters, multiply the foot value by 30.48. The formula is: cm = feet × 30.48. For example, 6 feet × 30.48 = 182.88 centimeters exactly.
For mixed feet-and-inches inputs, use: cm = (feet × 30.48) + (inches × 2.54). Example: 5 ft 9 in = (5 × 30.48) + (9 × 2.54) = 152.4 + 22.86 = 175.26 cm. The constant 30.48 is exact — derived from 1 inch = 2.54 cm × 12 inches per foot — established by the International Yard and Pound Agreement of 1959. Because 30.48 is a terminating decimal, every foot value converts to an exact, finite decimal in cm with no rounding required.
5 feet equals exactly 152.4 centimeters. The calculation: 5 × 30.48 = 152.4 cm — a perfectly exact, terminating result.
152.4 cm is the precise metric equivalent of 5 feet and appears in clothing size charts, building code minimum clearance heights, medical height references, and sporting eligibility tables. Use the 5 ft preset chip in the calculator for the full unit breakdown.
6 feet equals exactly 182.88 centimeters. The calculation: 6 × 30.48 = 182.88 cm — exact, no rounding.
Note: 183 cm (a common approximation) is not exactly 6 feet — it is 0.12 cm more. For casual conversation this difference is negligible, but for medical records, official sports registration, and architectural documents, use the exact 182.88 cm value. Use the 6 ft preset chip in the calculator for the full breakdown.
5 feet 7 inches equals exactly 170.18 centimeters. The calculation: (5 × 30.48) + (7 × 2.54) = 152.4 + 17.78 = 170.18 cm.
5 ft 7 in (170.18 cm) is near the average adult male height in many countries and is a widely cited benchmark on medical BMI charts. To enter this value in the calculator, convert to decimal feet: 5 + (7 ÷ 12) = 5.5833… ft. The composite output will confirm “5 ft 7.0 in” verifying the entry is correct.
5 feet 10 inches equals exactly 177.8 centimeters. The calculation: (5 × 30.48) + (10 × 2.54) = 152.4 + 25.4 = 177.8 cm exactly.
177.8 cm is near the average adult male height in the United States. In decimal feet, 5 ft 10 in = 5.8333… ft. You can also compute it from the 6 ft anchor: 6 ft = 182.88 cm, minus 2 inches (2 × 2.54 = 5.08 cm) = 177.8 cm. Use the look-up table in this page for all heights from 5 ft 0 in through 6 ft 11 in without manual calculation.
The metric definition of the foot was established by the International Yard and Pound Agreement of 1959, signed by the U.S., U.K., Canada, Australia, New Zealand, and South Africa. Under that treaty, 1 inch = 2.54 cm exactly. Since 1 foot = 12 inches: 1 foot = 12 × 2.54 = 30.48 cm exactly.
The full chain of exact definitions: 1 inch = 25.4 mm = 2.54 cm → 1 foot = 12 inches = 304.8 mm = 30.48 cm → 1 yard = 3 feet = 914.4 mm = 91.44 cm → 1 mile = 1760 yards = 160934.4 cm. Every link is exact. The result is a defined constant — not a measurement — recognized by the U.S. NIST and the International Bureau of Weights and Measures (BIPM).
Use the formula: cm = (feet × 30.48) + (inches × 2.54). Convert each component separately and add them. Examples:
5 ft 6 in = (5 × 30.48) + (6 × 2.54) = 152.4 + 15.24 = 167.64 cm · 6 ft 2 in = (6 × 30.48) + (2 × 2.54) = 182.88 + 5.08 = 187.96 cm. To use the calculator: enter decimal feet by dividing inches by 12 and adding to feet (e.g. 5 ft 6 in = 5.5 ft; 6 ft 2 in = 6.167 ft). The composite ft & in output confirms your decimal input in mixed format automatically.
Because the conversion factor 30.48 is itself a terminating decimal, multiplying any foot value by it always produces a terminating decimal result in centimeters. This is the “clean” direction of the foot–centimeter conversion: 1 ft = 30.48 cm exactly, 5 ft = 152.4 cm exactly, 6 ft = 182.88 cm exactly, 10 ft = 304.8 cm exactly. No rounding is required at any step.
This contrasts with the reverse direction (cm ÷ 30.48), which produces non-terminating repeating decimals for most cm values — for example, 1 cm = 0.032808398950… ft (repeating). In feet-to-cm conversions, displayed precision is a presentational preference, not a mathematical requirement. Every decimal shown by this calculator is exactly correct to 15 significant figures.
The foot is an imperial unit equal to 12 inches = 30.48 cm, used primarily in the United States for road distances, building dimensions, and heights, and informally for personal height in the United Kingdom. The centimeter is an SI (metric) unit equal to one-hundredth of a meter, used globally for heights and dimensions in medical, scientific, and official records.
A foot is a much larger unit than a centimeter — 1 ft = 30.48 cm, while 1 cm = 0.03281 ft. In everyday height terms: a 6 ft person (182.88 cm) is the same person whether described in feet or centimeters. The framing differs — “six foot” sounds tall to an American while “183 cm” might sound unremarkably close to 180 cm to a European — but the physical height is identical.
The calculator accepts decimal feet. To enter a feet-and-inches value, divide the inches by 12 and add to the whole feet: decimal ft = feet + (inches ÷ 12).
Common conversions: 5 ft 0 in = 5.000 ft · 5 ft 3 in = 5.250 ft · 5 ft 6 in = 5.500 ft · 5 ft 9 in = 5.750 ft · 6 ft 0 in = 6.000 ft · 6 ft 3 in = 6.250 ft · 6 ft 6 in = 6.500 ft. The composite “Ft & In” output in the results panel automatically confirms what your decimal input means in mixed format — so if you entered 5.5 ft and see “5 ft 6.0 in” in the composite output, the entry is correct.
The calculator uses the exact relationship 1 foot = 30.48 cm with double-precision floating-point arithmetic, accurate to approximately 15 significant digits. Because multiplying by 30.48 always produces a terminating decimal, every result is mathematically exact — the only rounding that occurs is at the display step, based on your chosen precision.
For medical records and sports documentation, 1–2 decimal places in cm provide sub-millimeter accuracy. For architectural drawings and precision manufacturing, 3–4 decimal places give sub-0.1 mm accuracy. The composite ft & in result is derived from the full-precision foot value, not a rounded intermediate, so it accurately reflects your original input. The downloadable PDF records all outputs, your precision setting, and the conversion standard for a complete auditable document.
Accuracy note: The HomeExpertly Feet to Centimeters Converter uses the exact international conversion relationship of 1 inch = 2.54 centimeters (therefore 1 foot = 30.48 cm exactly), as established by the 1959 International Yard and Pound Agreement and recognized by the U.S. National Institute of Standards and Technology (NIST) and the International Bureau of Weights and Measures (BIPM). Because the conversion factor 30.48 is a terminating decimal, multiplying any foot value by it produces a mathematically exact result in centimeters; displayed results are rounded only at the display step as a presentational preference. All calculations are precise to the decimal places you select (up to 8). The composite feet-and-inches result is derived from the full-precision value without intermediate rounding. Results are for informational and reference purposes only. For applications where measurement accuracy is critical — including but not limited to medical diagnosis, clinical dosing, architectural construction, manufacturing tolerances, legal documentation, building permits, official sports registration, or passport and visa applications — always verify your conversions independently using calibrated measuring instruments or authoritative reference documents. HomeExpertly is not responsible for any consequences arising from the use of these conversions, including measurement errors in medical, construction, legal, or sporting contexts.
