Cubic units: 1 m³ is 1,000,000 cm³
You learn to convert cubic units, like m³ to cm³: a cubic metre is 100 cm by 100 cm by 100 cm.
How to work it out
- 1 m is 100 cm, so 1 m³ is 100 × 100 × 100 = 1,000,000 cm³.
- To cm³, multiply by 1,000,000.
- To m³, divide by 1,000,000.
4 m³ = ? cm³
- 1 m³ = 1,000,000 cm³.
- Multiply by 1,000,000: 4 × 1,000,000 = 4,000,000.
- It is 4,000,000 cm³.
Another example
5,000,000 cm³ = ? m³
- You go to the bigger unit, so divide by 1,000,000: 5,000,000 ÷ 1,000,000 = 5.
- It is 5 m³.
