Chapter 8: Weight and Capacity

Visit any grocery shop. Sugar in kilograms, oil in litres, biscuits in grams, milk in millilitres. Weight tells how heavy something is. Capacity tells how much liquid a container holds. Both are measured with their own units.

In this chapter we learn to measure, add, subtract, and convert weights and capacities. By the end, you will be able to read any packet label and instantly know how much you are buying.
