### Year 6: Measuring

Measuring Length

Most things we now measure in metric units. However for distances to towns and people’s heights we tend to still use imperial measurements.

The length of my pencil is 19cm

My dad is 6 foot 2 inches tall (6’ 2”)

Newcastle is 16 miles away.

Understanding Length

This digit is worth 10m. There are 10 of these in 100m.

This digit is worth 1km. There are 10 of these in 10km

This digit is worth 100m. There are 10 of these in 1km

This digit is worth 1m. There are 10 of these in 10 metres.

This digit is worth 10km.

…and 1,000 metres in a kilometre!

Understanding Length

Remember:

10mm = 1cm

100cm = 1 metre

1,000 metres = 1km

Click on the question mark to find out the missing measurement.

Choosing Units of Measurement

Which unit of measurement would you use to measure these objects?

The length of my fingernail

The distance to Manchester

The length of the classroom

The length of a pencil

The distance to your holiday destination

The height of a building

The thickness of a book

Measuring Capacity

Capacity is measured in millilitres (ml).

There are 1,000ml in a litre.

Click on the object to see how many ml everyday objects use.

A jug contains 1,000ml (1 litre)

A teaspoon of medicine contains 5ml.

A ‘pint’ of milk contains 568ml of milk.

A soft drink can contains 300ml

A family bottle of lemonade contains 2 litres.
