How it works

Feet and inches combine into a single length by converting the feet to inches (×12) and adding the inches. From there, one inch is exactly 2.54 cm, so the metric conversion is a single multiply.

total inches = feet × 12 + inches
cm = total inches × 2.54 · m = cm ÷ 100

Worked example

5 ft 9 in is (5 × 12 + 9) = 69 inches, which is 69 × 2.54 = 175.26 cm (about 1.75 m).
