 UNITS OF MEASUREMENT

What we will learn today:

- The differences between the Metric and Imperial system.

- Which units are most appropriate for measuring/weighing different items

- How to use the 10,100 or 1000 conversions between units of length, mass and capacity

- How to convert between each common metric unit

Here is a list of imperial units that are sometimes used alongside metric units

What units do we use in the metric system for…

Capacity

Weight

Length

Which metric unit would you use to measure the weight of a sandwich?

Which metric unit would you use to measure water in a kettle?

Which metric unit would you use to measure the fence around a garden?

Which metric unit would you use to measure the volume of a can of Coke?

Which metric unit would you use to measure the distance between London and Cardiff?

HOW DO WE CONVERT BETWEEN 

METRIC UNITS?

DO WE MULTIPLY OR DIVIDE?

BY 10, 100 OR 1000?

Smaller unit to a larger unit = division

eg cm to m

Larger unit to a smaller unit = multiplication

eg km to m
