Imperial Units


Notes and Guidance

Children need to know and use the following facts:

• 1 foot is equal to 12 inches

• 1 pound is equal to 16 ounces

• 1 stone is equal to 14 pounds

• 1 gallon is equal to 8 pints

• 1 inch is approximately 2.5 cm

They should use these to perform related conversions, both within imperial measures and between imperial and metric.

When do we use imperial measures instead of metric measures?

Why are metric measures easier to convert than imperial measures?
