USING MEASURES

HOW MANY METRIC UNITS
CAN YOU REMEMBER?

RECAP

You have 2 minutes to write down as many metric conversions as you can remember!

When we work with metric units, we must always check that we're using the same unit throughout the question. Units in a calculation can't be mixed. Also check what unit is given on the answer line!

Example 1

You have a piece of ribbon that measures 1.35m. You need to use 62cm for a project. How many centimetres are you left with?

Example 2

A worktop is 7000mm long. I want the worktop to be 5.5m long. How many metres do I need to cut off?
