Unit conversion practice for 11+ Maths: Converting Units of Measure
19 October 2026
Why unit conversion matters
Converting units of measure is a key part of the 11+ Maths curriculum. Children are expected to switch confidently between units for length, mass, capacity, and time. Getting comfortable with these conversions helps with word problems and builds a strong foundation for later maths topics.
Common units and conversions
The 11+ often covers metric units: kilometres, metres, centimetres and millimetres for length; kilograms and grams for mass; litres and millilitres for capacity; and hours, minutes, and seconds for time. Children should know when to multiply or divide by 10, 100, or 1,000, and remember that time conversions use 60, not 100.
Supporting practice at home
Encourage your child to say out loud what they are converting and why. Use real-life examples. Measuring ingredients, timing activities, or checking distances. Ask them to explain their steps to spot any misunderstandings. Practising with a mix of written and spoken questions builds both speed and confidence.
Ideas for practice questions
Try questions like: 'Convert 2.5 kilograms to grams.' 'How many minutes are in 2 hours and 15 minutes?' 'Change 1,200 millilitres into litres.' Mix in word problems, such as recipes or journeys, to help your child apply their skills in context.
Key insight: Regular practice with unit conversions not only sharpens calculation skills, but also develops careful reading and logical thinking. These are essential for tackling multi-step problems in the 11+.
