Learn

The mass of an object tells you how heavy something is. You use grams (g) and kilograms (kg) to measure mass.

  • Grams are used when you weigh a lighter item, like an apple or banana.

  • Kilograms are used when measuring the mass of a heavier object, like a box of toys or yourself.

1000 g = 1 kg

Top tip

You can use the greater than (>) , equal to (=) or less than (<) signs to help you compare the mass of two objects.

Don’t forget, the tip of the arrow always points to the smaller number.
