To convert metres to kilometres, we divide by 1000, since 1 kilometre = 1000 metres - so 2500 m = 2.5 km.
Quick revision
Remember these!
- To convert cm to m, divide by 100.
- 250 cm = 2.5 m.
- To convert m to km, divide by 1000.
- 2500 m = 2.5 km.
- To convert m to cm, multiply by 100.
- To convert km to m, multiply by 1000.
- 3 m = 300 cm, and 4 km = 4000 m.
- Conversion helps compare measurements correctly.
