Question types: Converting measures with decimals

Rule: Measures with decimals

1 km = 1000 m, 1 kg = 1000 g, 1 l = 1000 ml, 1 m = 100 cm. To a smaller unit multiply, to a larger one divide.

Multiplying by 10, 100 or 1000 moves the decimal point 1, 2 or 3 places to the right.

Example: 2.5 km = 2500 m; 750 g = 0.75 kg

Watch out: 0.3 kg is not 300 kg or 3 g: 0.3 × 1000 = 300 g.
