Converting units
| Quantity | Fact |
|---|---|
| length | 10 mm = 1 cm; 100 cm = 1 m; 1 000 m = 1 km |
| mass | 1 000 g = 1 kg; 1 000 kg = 1 t |
| capacity | 1 000 ml = 1 ℓ |
| time | 60 s = 1 min; 60 min = 1 h |
Big → small: multiply. Small → big: divide. 4,2 km = 4 200 m; 750 g = 0,75 kg.

With decimals: × 1 000 moves the comma three places to the right.
Remember this and test yourself
- Big to small: multiply.
- Small to big: divide.
- Know the numbers: 10, 100, 1 000, 60.
Write these points in your book. Read them again the night before the test.
