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
1 pint = 4 gillsIn the United States, there are variations on the size of each imperial unit. It would be very expensive for the UK and the US to change to metric units.
3. How do you convert between the units for capacity in the metric system to the Imperial system?
