Measurement & data

What you’ll practice

Convert exact quantities between m and cm, km and m, kg and g, and L and mL.

Check the units before choosing a factor. Smaller units need a larger number to describe the same amount; larger units need a smaller number.

How this skill works

1 m = 100 cm, 1 km = 1,000 m, 1 kg = 1,000 g, and 1 L = 1,000 mL.

Multiply when converting to the smaller unit. Divide when converting to the larger unit. Keep the same physical quantity.

Worked example

Convert 350 cm to metres.
  1. 100 cm = 1 m.
  2. 350 ÷ 100 = 3.5.
  3. 350 cm = 3.5 m.

Answer: 3.5 m

Teaching notes

  • Check both the factor and its direction.

Answers and steps
  1. 0.212 kg
    1. 1000 g = 1 kg. Divide: 212 ÷ 1000 = 0.212 kg.
  2. 0.419 L
    1. 1000 mL = 1 L. Divide: 419 ÷ 1000 = 0.419 L.
  3. 6000 mL
    1. 1 L = 1000 mL. Multiply: 6 × 1000 = 6000 mL.
  4. 2.56 m
    1. 100 cm = 1 m. Divide: 256 ÷ 100 = 2.56 m.
  5. 0.494 km
    1. 1000 m = 1 km. Divide: 494 ÷ 1000 = 0.494 km.
  6. 196000 mL
    1. 1 L = 1000 mL. Multiply: 196 × 1000 = 196000 mL.
  7. 441000 mL
    1. 1 L = 1000 mL. Multiply: 441 × 1000 = 441000 mL.
  8. 1.87 m
    1. 100 cm = 1 m. Divide: 187 ÷ 100 = 1.87 m.
  9. 27900 cm
    1. 1 m = 100 cm. Multiply: 279 × 100 = 27900 cm.
  10. 0.124 km
    1. 1000 m = 1 km. Divide: 124 ÷ 1000 = 0.124 km.
  11. 4.68 m
    1. 100 cm = 1 m. Divide: 468 ÷ 100 = 4.68 m.
  12. 139000 mL
    1. 1 L = 1000 mL. Multiply: 139 × 1000 = 139000 mL.
