Next week the children will be looking at measures. They will be understand and use approximate equivalences between metric units and common imperial units such as inches, pounds and pints.
Converting between metric and imperial units
Here are some examples of metric and imperial measures of length, mass and capacity:
|Length||mm, cm, m, km||inch, foot, yard, mile|
|Mass||mg, g, kg||ounce (oz), pound (lb), stone|
|Capacity||ml, cl, l||pint, gallon|
You will be expected to know some common conversions between metric and imperial units. Some of these are shown below, but check with your teacher which ones you need to learn.
- 1 km = 5/8 mile
- 1 m = 39.37 inches
- 1 foot = 30.5 cm
- 1 inch = 2.54 cm
- 1 kg = 2.2 lb
- 1 gallon = 4.5 litres
- 1 litre = 1 3/4 pints
