| 1 cm = 10 mm (one centimetre = ten millimetres) | |||
| 1 m = 100 cm (one metre = hundred centimetres) | |||
| 1 km = 1000 m (one kilometre = one thousand metres) | |||
| 1 km = 1000 000 mm (one kilometre = one million millimetres) | |||
| 1000 km = 1000 000 000 mm (one thousand kilometres = one billion millimetres) | |||
