Converting Units Worksheets: Year 6 Maths

Year 6 maths worksheets on converting units of measure, money and time: 36 questions in three levels (All, Most, Some) with answers. Free PDF.

7-page A4 PDF from the Tiger Shark Education question bank. All: Know the facts for converting units, including time. Most: Convert between metric units, including decimals. Some: Convert between units, including money and miles. Each level is two pages of six questions, each with a squared working area, and the last page has every answer, with short working for multi-step questions. Each level is also available as its own 3-page PDF. Example questions from the Some level: Convert 25 pence to pounds / Convert 5 miles to km.

What is converting units? Converting units means changing a measurement into a different unit of the same type: 2.5 km = 2,500 m, 750 g = 0.75 kg, 1,500 ml = 1.5 l. Metric conversions are based on 10, 100 and 1,000, so they rely on multiplying and dividing by these numbers. Year 6 pupils convert using decimals to three places.

Common mistakes and tips: Children often multiply when they should divide, or use the wrong conversion factor (100 instead of 1,000 for grams to kilograms). Ask them to check whether the number should get bigger (converting to a smaller unit) or smaller. A conversion table on the wall is useful scaffolding at first.

This topic is part of the Year 6 National Curriculum for maths, and it regularly appears on the KS2 SATs papers. The All, Most and Some levels let you check basic fluency first and then move on to the multi-step, contextual questions found on the reasoning papers.

How teachers use these sheets: as a lesson’s independent task, as a starter to revisit a topic from earlier in the year, or as a revision pack in the weeks before the SATs. Children can mark their own work with the answer page, then explain one mistake to a partner to deepen understanding.

Reasoning and explanation: once children can answer the questions, ask them to explain their method to a partner or write a short explanation of one answer. The SATs reasoning papers include ‘explain how you know’ questions, and talking about methods deepens understanding far more than repeating calculations.

Use All for children working towards the expected standard, Most for secure Year 5 skills and Some for SATs-standard practice: three entry points to the same lesson. Suits whole-class differentiation, intervention groups, homework and SATs revision, and upper KS2 generally.
