Grade 4 Math

Mass units

Practise g, kg, and t conversions, mixed-unit answers, and comparisons of mass.

How to solve this

  • The key conversions are 1 kg = 1000 g and 1 t = 1000 kg.
  • Convert to the smaller unit when comparing: 2 kg is 2000 g, so it is heavier than 1800 g.
  • Mixed notation is useful for remainders: 2500 g is 2 kg 500 g.

Examples

1 kg = __ g

1000

3 t = __ kg

3000

2500 g

2 kg 500 g
