1. What is a litre?
Think of a litre as the space occupied by a cube of side 10 cm.
Two litres is the size of a large milk container in New Zealand.
2. What other systems are there for measuring capacity?
The United Kingdom uses the IMPERIAL system for measuring capacity.
The units in this system include: gallons, quarts and pints.
1 gallon = 8 pints
1 quart = 2 pints
