How to convert centimetres to metres
One centimetre equals 0.01 metres, so multiply the number of centimetres by 0.01:
m = cm × 0.01
cm = m ÷ 0.01 (1 m = 100 cm)
Example: 30 cm → 30 × 0.01 = 0.3 m.
Going the other way, divide by 0.01, or multiply by 100; the metres to centimetres converter does it for you.
Everyday values
| Centimetres | Metres | For example |
|---|---|---|
| 30 cm | 0.3 m | a ruler |
| 100 cm | 1 m | one metre |
| 150 cm | 1.5 m | 1.5 m |
| 175 cm | 1.75 m | an average adult man in many countries |
| 200 cm | 2 m | 2 m |
When you need this conversion
Divide centimetres by 100 to get metres. Height is often given in centimetres (175 cm) on forms and in metres (1.75 m) in BMI formulas; the BMI calculator accepts centimetres directly.
