Maths and measurements
By Admin, on 17 May 2021
At the end of the Second World War, a number of different systems of measurement were in use throughout the world. In 1960, the 11th General Conference on Weights and Measures synthesised the results of a 12-year study and created a new system that was named the International System of Units, abbreviated SI from the French name, Le Système International d’Unités. The SI is the only system of measurement with an official status in nearly every country in the world, with some countries still using different measurement systems, such as the Imperial measurement system used in the UK.
Table 1 shows the units of measurements and some derived units for length, mass, and volume in the two systems:
International System of Units (SI) | Imperial System | |
Length | Metre, centimetre, millimetre, kilometre | inch, feet, yard, mile |
Mass | Kilogram, gram, ton | pound, ounce, stone |
Volume | Litre, millilitre | pint, gallon |

Your child might be too young to learn all of these yet. However, your child will hear these measures being used all of the time in their daily lives. Showing your child how these are used in your everyday life and how they relate to each other (how many centimetres in a meter, how many millimetres in a foot) will help your child develop a full understanding of how and when we use these words. Moreover, you might want to create, with your child, visual resources to support their understanding of measurements in different systems and their relationships (Figure 1 and 2).
