Mathematics Ratio & Proportionusually ages 11–12

Unit Conversions

Convert freely between related standard units of measurement (time, length, area, volume/capacity, mass) using decimal notation to up to three decimal places where appropriate

How to tell they’ve got it

Tick these off as you see them — no test required.

Convert between area units such as cm² and m² using the square of the linear scale factor
Perform multi-step conversions (e.g. convert 2.5 hours to seconds via minutes)
Convert volume units such as cm³ to litres and explain the relationship
