Common Heights
What is a Feet to CM?
The Feet & Inches to Centimetres Converter is a dedicated height conversion tool that accepts a measurement expressed as separate feet and inches values and returns the exact equivalent in centimetres, metres, and total inches. Unlike a general-purpose unit converter that takes a single decimal number, this tool mirrors the way height is actually stated in everyday life — "five feet eleven inches," not "5.9167 feet" — so you never have to do any intermediate arithmetic yourself.
The converter is built around a simple, exact relationship: one inch is defined as exactly 2.54 centimetres, with no approximation involved. Enter 5 in the Feet field and 11 in the Inches field, and the result panel instantly displays 180.34 cm, 1.8034 m, and 71 total inches. A quick-reference grid below the inputs shows 18 common heights from 4'11" to 6'4" with their centimetre equivalents, so you can find the answer for the most frequently looked-up heights without typing at all.
The tool is designed for the specific gap that exists in India and across South Asia: most people know their height in feet and inches from everyday conversation, family habit, and clinic visits, but a growing number of official documents — passports, driving licences, Aadhaar health records, government recruitment notices, and insurance forms — require height in centimetres or metres. This converter closes that gap in two keystrokes.
For broader unit conversions involving length, the Length Converter handles the full range of metric and imperial units, including kilometres, miles, yards, and nautical miles.
How to use this Feet to CM calculator
Enter your feet value in the Feet input field on the left. Type a whole number — most heights are 4, 5, or 6 feet. You can enter 0 if the height is under one foot (for infant measurements, for example).
Enter your inches value in the Inches input field on the right. Type a value from 0 to 11. If your height is a whole number of feet with no remaining inches, leave this field at 0.
Read the result in the output panel directly below the inputs. You will see three values: Centimetres (e.g. 180.34 cm), Metres (e.g. 1.8034 m), and Total Inches (e.g. 71 in). All three update instantly as you type.
Use the copy button next to any output value to copy it to your clipboard. This is the fastest way to transfer the centimetre value into a government form, health app, or spreadsheet without risk of transcription error.
Consult the quick-reference grid below the converter for the 18 most common heights from 4'11" to 6'4". Each row shows the height in feet-and-inches alongside its exact centimetre equivalent. If your height is in this range, you can read the answer directly from the grid without using the input fields.
Share or bookmark the result by copying the page URL. The converter writes your feet and inches values as URL parameters, so the link encodes the full conversion and opens with your values pre-filled for anyone you send it to.
Formula & Methodology
### The conversion formula The entire conversion rests on a single exact relationship: > 1 inch = 2.54 cm (exactly, by international definition) Given a height expressed as F feet and I inches:Total inches = (F × 12) + I Centimetres = Total inches × 2.54 Metres = Centimetres ÷ 100Worked example — 5 feet 11 inches:Total inches = (5 × 12) + 11 = 60 + 11 = 71 inches Centimetres = 71 × 2.54 = 180.34 cm Metres = 180.34 ÷ 100 = 1.8034 m### Why 2.54 is exact The factor 2.54 is not a rounded approximation — it is a legally binding definition. In 1959, the six English-speaking nations that used imperial units (the United States, the United Kingdom, Australia, Canada, New Zealand, and South Africa) signed the International Yard and Pound Agreement, which redefined the yard as exactly 0.9144 metres. Since one yard = 3 feet = 36 inches, this means one inch = 0.9144 ÷ 36 = 0.0254 m = 2.54 cm, exactly. The 1959 definition resolved a small but real discrepancy between the US survey inch and the UK imperial inch, and it is the value used by every standards body, measurement laboratory, and SI-compliant calculator today. ### Reference table — 10 common heights | Height (ft & in) | Total Inches | Centimetres | Metres | |---|---|---|---| | 4′ 11″ | 59 in | 149.86 cm | 1.4986 m | | 5′ 0″ | 60 in | 152.40 cm | 1.5240 m | | 5′ 2″ | 62 in | 157.48 cm | 1.5748 m | | 5′ 4″ | 64 in | 162.56 cm | 1.6256 m | | 5′ 6″ | 66 in | 167.64 cm | 1.6764 m | | 5′ 8″ | 68 in | 172.72 cm | 1.7272 m | | 5′ 10″ | 70 in | 177.80 cm | 1.7780 m | | 5′ 11″ | 71 in | 180.34 cm | 1.8034 m | | 6′ 0″ | 72 in | 182.88 cm | 1.8288 m | | 6′ 2″ | 74 in | 187.96 cm | 1.8796 m | All centimetre values in this table are exact results of the formula Total inches × 2.54, rounded to two decimal places for display. ### Precision notes - The converter displays centimetres to two decimal places. For most official purposes (passport, driving licence, recruitment forms) the value is rounded to the nearest whole centimetre: 180.34 cm is written as 180 cm. - There is no floating-point approximation in the arithmetic — the 2.54 factor is represented exactly in IEEE 754 double-precision arithmetic for the values in the human height range. - The metre output is derived by dividing the centimetre result by 100; for passport and visa forms, the standard presentation is two decimal places (e.g. 1.80 m). For calculating your Body Mass Index once you have your height in centimetres, use the BMI Calculator, which accepts height directly in cm or feet-and-inches.
