How to convert cm to feet and inches
Divide the height in centimeters by 2.54 to get total inches, then divide by 12. The whole number is feet and the remainder is inches. For example, 175 cm ÷ 2.54 = 68.9 inches, which is 5 feet 8.9 inches – usually written 5′9″.
How to convert feet and inches to cm
Multiply the feet by 12, add the inches and multiply the total by 2.54. For example, 5 ft 7 in = 67 inches × 2.54 = 170.18 cm. Because an inch is defined as exactly 2.54 cm, the result is exact.
