Level 3-4 Shapes - Imperial and Metric
For KS3 Maths you'll need to understand both imperial and metric units of measurement. Imagine calculating the area of some shapes in metric units like centimetres or metres. Now convert your answers to imperial. How many centimetres make an inch or how many yards in a metre? Hopefully, this quiz will make things simple.
Metric units are all based on powers of ten like 100s or 1,000s. They include metres, kilograms and litres. They're based on decimalsisation because tens are so much easier to work with. The older, and now mostly outdated, imperial system has units such as yards, pounds and pints with seemingly random values. Despite this, the old system is still in use and you will most certainly have come across pounds and ounces, miles or the Fahrenheit temperature scale. It is useful to know some rough metric equivalents of common imperial units. That will make your life so much easier. Here is a list of some approximate equivalent values:
- 1kg = 2.2lb
- 1 litre = 1.75 pints
- 1 gallon = 4.5 litres
- 5 miles = 8km
- 1 inch = 2.54cm
- 1 foot = 20cm
- 12 inches in a foot
- 16 ounces in a pound (lb)
- 14lb in a stone
