2. DISTANCE
There are two systems for measuring distance in the English-
speaking world:
a) metric
10 millimetres (mm) = 1 centimetre (cm)
100 centimetres = 1 metre (m)
1000 metres = 1 kilometre (km)
b) imperial/US
12 inches (in) = 1 foot (ft)
3 feet = 1 yard (yd) (approximately 1 metre)
1760 yards = 1 mile (approximately 1.6 km)
