Metric Length Unit Conversions

Convert carefully between millimetres (mm), centimetres (cm), metres (m) and kilometres (km). Show working for problems that need more than one step.

Metric Conversion Practice

1.Convert 4.8 metres to centimetres.
2.Convert 3,650 millimetres to metres.
3.Convert 8.35 kilometres to metres.
4.Convert 1,275 centimetres to metres.
5.Which measurement is equivalent to 7,400 metres?
  • 0.74 km
  • 7.4 km
  • 74 km
  • 740 km
6.Select every true metric length equivalence.
  • 1,000 mm = 1 m
  • 10 cm = 1 m
  • 1 km = 1,000 m
  • 100 m = 1 km
  • 1 cm = 10 mm

Match Equivalent Lengths

Write the letter of the matching length beside each measurement.
