Definition: Height is often written as feet + inches (imperial) or meters + centimeters (metric). This converter uses exact factors: 1 in = 2.54 cm and 1 ft = 0.3048 m (12 in).
What it calculates: Human height between feet+inches and meters/centimeters using exact inch and foot definitions.
Inputs: Feet and inches, or meters/centimeters
Outputs: Equivalent height in the opposite system
Formula: m = (ft × 0.3048) + (in × 0.0254) · total_in = cm ÷ 2.54 · ft = ⌊total_in ÷ 12⌋

Frequently asked questions

Key distinctions behind the conversion.

How do you convert feet and inches to meters?

m = (ft × 0.3048) + (in × 0.0254). Example: 5 ft 10 in → 1.778 m (177.8 cm).

How do you convert centimeters to feet and inches?

Divide cm by 2.54 to get total inches, then ft = floor(total_in ÷ 12) and in = remainder.

Is 1 foot exactly 0.3048 m?

Yes. The international foot is defined as exactly 0.3048 m (12 × 0.0254 m).

Does this run locally?
