Measuring Length Metric Units of Measurement Imperial Units of Measurement Millimetres (mm) Centimetres (cm) Metres (m) Kilometres (km) Inches Feet yards miles 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. www.visuallessons.com

Choosing Units of Measurement Which unit of measurement would you use to measure these objects? Height of your friend The distance to your holiday destination The thickness of a book The length of a pencil The height of a building The distance to Manchester The length of my fingernail The length of the classroom Millimetres (mm) Centimetres (cm) Metres (m) Kilometres (km) www.visuallessons.com

Capacity is measured in millilitres (ml). 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. www.visuallessons.com
