Weight and Capacity

Weight (more precisely, mass) tells us how heavy something is. We measure it in grams (g) and kilograms (kg). There are 1,000 grams in one kilogram, so 2.5 kg = 2,500 g.

Capacity is the amount a container can hold. We measure liquids in millilitres (ml) and litres (l). There are 1,000 ml in 1 litre. A large bottle of water holds 1,500 ml = 1.5 l.
