Which overall statement about measurement is CORRECT?

  1. A Length is measured in metres and centimetres, weight in kilograms and grams, and capacity in litres and millilitres; larger units contain 1000 (or 100) of the smaller units
  2. B All things are measured in metres
  3. C 1 kg = 100 g
  4. D Weight is measured in litres

Answer: A — Length is measured in metres and centimetres, weight in kilograms and grams, and capacity in litres and millilitres; larger units contain 1000 (or 100) of the smaller units

This sums up the topic: we choose the right unit for what we measure - length (m, cm, km), weight (kg, g) and capacity (L, ml); and we remember 1 m = 100 cm, 1 km = 1000 m, 1 kg = 1000 g and 1 L = 1000 ml.
