How it works
Exact factor: 1 inch = 2.54 cm, by international definition since 1959, so there is no rounding error in the formula — only in how many decimals you keep. Quick estimate: multiply by 2.5, which is about 1.6 % too low (65 in → 162.5 cm instead of 165.1 cm).
To convert height, turn feet and inches into inches first: 5 ft 10 in is 5 × 12 + 10 = 70 in, which is 177.8 cm.
Examples
- TV
- 55 in = 139.7 cm.
- Jeans
- 32 in = 81.28 cm.
Common uses
