Metric & Imperial Conversion

Mathematics · Measurement · conceptual

Understand and use approximate equivalences between metric units and common imperial units (inches, pounds, pints)

Sign in to track this

What mastery looks like

  • State that 1 inch ≈ 2.5 cm and use this to estimate length in inches
  • Know that 1 kg ≈ 2.2 pounds and estimate a person's weight in pounds
  • Convert approximately between litres and pints (1 litre ≈ 1.75 pints)

Check your understanding

If Metric & Imperial Conversion hears that a baby weighs 7 pounds, can they give a rough idea of that in kilograms — using the approximate conversion they know?
