About the Height Converter
Height is one of the few measurements where Americans mix two units (5 ft 10 in), while most of the world uses centimeters (178 cm). This converter handles both directions, which is useful for passports and visa forms, medical and fitness apps, dating profiles, sports rosters and clothing size charts.
Because a single unit, centimeters, is easier to compare, the result also lists nearby heights in both systems so you can see how each extra inch adds 2.54 cm.
Formula
total inches = feet × 12 + inches
centimeters = total inches × 2.54
feet = ⌊(cm ÷ 2.54) ÷ 12⌋, inches = remaining (cm ÷ 2.54) mod 12
The inch has been defined as exactly 2.54 cm since 1959, so these conversions are exact; feet and inches are shown to the nearest half inch.
Example calculation
Using the default values:
- Convert = Feet & inches → cm / m
- Feet = 5 ft
- Inches = 10 in
the calculator returns:
- Centimeters: 177.8 cm
- Feet and inches: 5 ft 10 in
- Meters: 1.778 m
- Total inches: 70 in
