The metric system uses measurements that we often see every day. These are used to measure length, weight and capacity. You’ll often see these as grams, kilograms, millimetres, centimetres, metres, millilitres and litres.

The metric system is used all around the world because it is easy to understand. It uses tens, hundreds and thousands. This means it's a lot easier to understand, so converting weights and lengths isn’t as hard to do.

Our current form of the metric system is the most modern one. It’s the only system of measurement that is official in nearly every country in the world. This is important as it is also known as the International System of Units, abbreviated to SI. Having a standard unit of measurement is important so that everyone can understand each other. If a friend tells you they’re travelling 80 miles, or baking a cake that’s 800 grams, then you know what they mean.
