Choosing measurement units

Mathematics · Measurement · procedural

Choose and use appropriate standard units to measure length (m/cm), mass (kg/g), temperature (°C), and capacity (litres/ml) to the nearest appropriate unit

What mastery looks like

  • Measure the length of a table in centimetres using a ruler
  • Weigh an object in grams using a scale
  • Measure the capacity of a container in millilitres using a measuring jug

Check your understanding

If you ask Choosing measurement units whether to measure a swimming pool or a piece of paper in cm or m, can they pick the sensible unit for each — and explain why?
