Help your students prepare for their Maths GCSE with this free converting units of measure worksheet of 34 questions and answers
Metric unit conversion involves converting between metric units of measurement, for example between centimetres and millimetres, which are metric units of length. Measurement conversion might be done to make the measurement easier to understand or in order to perform calculations.
We use metric measurement units for length, mass and capacity. To convert metric measurements, we need to know the conversion rates for different units . For example, the metric conversions for converting units of length are 1km=1000m, 1m=100cm and 1cm=10mm . It can be helpful to look at a conversion chart which shows these values.
The metric system uses different prefixes to mean different things. Examples of these prefixes are milli, centi and kilo. Wherever milli is used, for example, it means 1000th of the unit, so 1 millilitres =0.001 litre and 1 millimetres =0.001 metre.
Converting metric units of area and volume is an extension of converting metric units of length. When converting between metric units of area, we need to square the conversion rate for the units of length.
For example, there are 10 millimetres in a centimetre so to convert from centimetres to millimetres we multiply by 10 . To convert from centimetres squared to millimetres squared we multiply by 10^2. Similarly, when converting between metric units of volume, we need to cube the conversion rate for the units of length.
Looking forward, students can then progress to additional conversion worksheets and other ratio and proportion worksheets, for example a ratio worksheet or a simplifying and equivalent ratios worksheet.
There will be students in your class who require individual attention to help them succeed in their maths GCSEs. In a class of 30, it’s not always easy to provide.
