Height Converter

Medical charts, apparel size guides, and sports bios often show height in both metric and imperial formats. This calculator routes everything through meters, then displays centimeters, millimeters, inches, or a feet+inches format without rounding drift.

How the conversion works

The inch is defined as exactly 25.4 millimeters, and the foot is 12 inches. From those definitions:

$1\,\text{in} = 0.0254\,\text{m} \qquad 1\,\text{ft} = 0.3048\,\text{m}$

To convert any height to meters, multiply by its meter factor; then convert from meters to the target unit with the inverse factor. The feet+inches codec splits or combines values so mixed numbers stay readable.

Units and conversions

Worked examples

1. 1.75 m to feet

$1.75 / 0.3048 \approx 5.7415\,\text{ft}$

2. 70 in to centimeters

$70 \times 2.54 = 177.8\,\text{cm}$

3. 5 ft 6 in to meters

$5.5 \times 0.3048 \approx 1.6764\,\text{m}$

Tips and pitfalls

• Use feet+inches for readability in the US, but keep an unrounded centimeter value for precise sizing.
• The US survey foot was retired in 2023; stick to the international foot (0.3048 m) unless a legacy map demands otherwise.
• When rounding, keep at least one decimal place for cm and two for inches to avoid size jumps.
