Measuring is a vital skill in KS3 Maths. When it comes to measuring distances, like the length or width of shapes, we need to use units of measurement. This quiz will test how well you know how these units relate to one another.

In maths, most distance measurements will be in one of four units - millimetres (mm), centimetres (cm), metres (m) or kilometres (km). There are 10 millimetres in a centimetre, 100 centimetres in a metre and 1,000 metres in a kilometre. It is easy to get mixed up with the number of noughts and decimal places when measuring length. You might also come across some imperial units of distance measurement like inches, feet, yards and miles. These are more complicated as they have seemingly random values. But don't worry - this quiz sticks to the metric system.

The more often you do a thing, the better at it you get. This quiz will give you plenty of practise on metric measurements of distance. Take your time and read each question carefully before you choose your answers. Good luck!
