Convert Between Metric and Imperial Units

In this activity, we will convert between imperial and metric units.

Imperial units can be converted into approximate metric equivalents by knowing the following conversions:

1 m = 3 ft
8 km = 5 miles
1 kg = 2.2 lbs
30 g = 1 ounce
1 litre = 2 pints

Example 1

Approximately how many metres are equivalent to 30 ft ?

1 m = 3 ft

3 ft = 1 m

3 x 10 = 30 ft, so 1 x 10 = 10 m

30 ft = 10 m

10 m = 30 ft

 

Example 2

Approximately how many km are equivalent to 17 miles ?

8 km = 5 miles

8/5 km = 1 mile 

8/5 km x 17 = 17 miles

27.2 km = 17 miles
