About Height Converter (Feet Inches To cm) Calculator

A height in feet and inches is first collapsed into a single number of inches — twelve inches to the foot — and then multiplied by 2.54 to reach centimetres, since the inch is defined as exactly 2.54 cm. Keeping the two steps separate is what makes the result exact rather than a two-part approximation.
