As part of your work in KS3 Maths on shapes, you will be asked to do some measurements. You'll be used to measuring areas, distances (like width or length) and volumes or capacities. One other thing you will have to measure is weight or mass.

Technically, there is a difference between 'weight' and 'mass', as you'll learn in your Physics classes. But in real life the two terms are usually taken to mean the same thing. As far as maths is concerned, both are measured in the same units - grams (g), kilograms (kg) and tonnes. There are 1,000 grams in a kilogram and 1,000 kilograms in a tonne so converting between them is quite simple - just divide or multiply by 1,000. You may also come across imperial units of weight, like ounces, pounds or tons. Don't worry - this quiz deals only with metric weights. There's a quiz all about imperial weights which you're no doubt looking forward to playing! Why not try it after this?
