Worked Calculation Examples
| Scenario | Result | Calculation Step |
|---|---|---|
| 5 ft 9 in to centimeters | 175.26 cm | (5 × 12 + 9) = 69 total inches. 69 × 2.54 = 175.26 cm. |
| 180 cm to feet and inches | 5 ft 10.87 in | 180 ÷ 2.54 = 70.87 total inches. 70.87 ÷ 12 = 5 ft with a remainder of 10.87 in. |
The Conversion Formula
1 inch equals exactly 2.54 centimeters. To convert feet and inches to centimeters, convert the total height to inches first (feet x 12 + inches), then multiply by 2.54. To convert centimeters to feet and inches, divide by 2.54 to get total inches, then divide by 12 for feet, keeping the remainder as inches.
A Worked Example
A height of 5 feet 9 inches equals 69 total inches (5 x 12 + 9), which converts to 69 x 2.54 = 175.26 centimeters. Going the other direction, 180 cm equals 180 / 2.54 = 70.87 inches, or 5 feet 10.87 inches.
