CEM & GL Style Reasoning: Converting Metric Units Example
23 October 2026
CEM and GL style reasoning questions often involve converting between metric units. It's important for your child to know the key facts and use logical steps to solve these problems confidently.
Worked example
A jug holds 2.5 litres of water. How many millilitres is this?
Step 1: Remember, 1 litre = 1,000 millilitres.
Step 2: To change litres to millilitres, multiply by 1,000.
Step 3: 2.5 × 1,000 = 2,500
The correct answer is 2,500 millilitres.
After working through this example, your child can spot when to multiply or divide to change between metric units. They are now ready to practise similar questions and build their confidence for the 11+ exam.
