Metric Conversions Learning Objectives Know some metric units

Metric Conversions Learning Objectives: • Know some metric units of measurements • Able to convert between metric units of length, mass and capacity • Able to convert between metric units of area and volume

Metric Units • What units of length do you know? • What units of mass do you know? • What units of capacity do you know?

Metric Conversions - LENGTH Examples: x 1000 km ÷ 1000 x 100 m x 10 cm ÷ 100 mm ÷ 10 • Convert 3 m to cm 3 x 100 = 300 cm • Convert 5. 7 km to m 5. 7 x 1000 = 5700 m • Convert 3. 6 km to cm 3. 6 x 1000 = 3600 m 3600 x 100 = 360000 cm

Metric Conversions - MASS Examples: x 1000 Tonne kg ÷ 1000 x 1000 g • Convert 5 g to mg 5 x 1000 = 5000 mg mg • ÷ 1000 Convert 2. 9 kg to g 2. 9 x 1000 = 2900 m • Convert 7. 6 tonnes to mg 7. 6 x 1000 = 7600 Kg 7600 x 1000 = 7600000 g 7600000 x 1000 = 760000 mg

Metric Conversions - CAPACITY Examples: x 100 ml cl l ÷ 100 • Convert 9 l to cl x 10 ÷ 10 9 x 100 = 900 cl • Convert 90 ml to cl 90 ÷ 10 = 9 cl • Convert 15300 ml to l 15300 ÷ 10 = 1530 cl 1530 ÷ 100 = 15. 3 l

Your turn…. • Convert the following units into the given units shown 1 m 3 = 1000 l 1 cm 3 = 1 ml 1) 1) 2) 2) 1) 3) 3) 2) 4) 4) 3) 5) 5) 4) 6) 6) 5)

Starter • Convert the following: • 3. 7 tonnes to kg • 0. 9 km to cm • 37350 ml to litres

Metric Conversions Learning Objectives: • Able to convert between metric units of length, mass and capacity • Able to convert between volume and capacity • Able to convert between metric units of volume

Metric Conversions • 1 m 3 = 1000 l x 1000 3 m • 1 cm 3 = 1 ml ÷ 1000 l

Metric Conversions • Examples: Convert 3700 l to m 3. • 3700 ÷ 1000 = 3. 7 m 3 • Convert 1. 73 cm 3 to l • = 1. 73 ml • 1. 73 ÷ 10 = 0. 173 cl • 0. 173 ÷ 100 =0. 00173 l Now try these… 1) 2) 3) 4) 5)

Starter • On whiteboards, convert the following: 6000 mg to g 7 m to cm 9 cm to mm 0. 5 l to ml 453, 000 g 3 to tonnes to kg 3 75 cm to ml 450 cl to l 370 m to km 190 ml to cl 8500 l to m 3

Metric to Imperial Conversions Learning Objectives: • Able to convert between volume and capacity • Able to convert between metric units of volume • Able to convert between metric and imperial units

Metric Conversions 1 cm VOLUME = 1 cm 3 = 10 mm VOLUME = 1000 mm 3 10 mm 1 cm x 1000 cm 3 mm 3 ÷ 1000

Metric Conversions = 1 m VOLUME = 1 m 3 100 cm VOLUME = 100000 cm 3 100 cm 1 m 1 m 100 cm x 100000 m 3 ÷ 100000 cm 3

Metric Conversions • Convert the following: a) b) c) d) e) 5 cm 3 to mm 3 9 m 3 to cm 3 1500 mm 3 to cm 3 960000 cm 3 to m 3 0. 07 m 3 to mm 3

Metric to Imperial Examples: Convert 5 kg to pounds (lbs) 5 x 2. 2 = 11 lbs Convert 16 miles to km 16 x 1. 6 = 25. 6 km
