An easy way to change between imperial and metric untis of lenght, weight and volume.

Updated on February 20, 2013

3 of the main conversions between metric and imperial conversions are:

5 miles = 8 kilometres (Length Conversion)

1kilogram = 2.2 pounds (Weight Conversion)

1 gallon = 4.5 litres (Volume Conversion)

Let’s look at some examples on converting between these imperial and metric units.

Example 1

Convert 15 miles into kilometres.

All you need to do is use the conversion 5 miles = 8 kilometres

15 ÷ 5 = 3

So 8 × 3 = 24 km

Example 2

Convert 15 kilograms into pounds.

This time you can use the conversion of 1kilogram = 2.2 pounds

All you need to do now is multiply 15 by 2.2:

15 × 2.2 = 33kg

Example 3

Convert 120 litres into gallons.

Here you need to use the conversion 1 gallon = 4.5 litres.

So to work out the amount of litres you need to divide by 4.5:

120 ÷ 4.5 = 26.7 gallons.

Example 4

Chris drives 32km to work every day. Work out the total distance that Chris drives to work assuming he works 5 day week.

Since you are changing between miles and kilometres again you need the conversion 5 miles = 8 kilometres.

First convert the distance he travels in one day into miles:

32 ÷ 8 = 4

4 × 5 = 20 miles

So in one day Chris drives 20 miles.

Now all you need to do is work out how many miles Chris drives in the whole week. You can do this by multiplying by 5:

20 × 5 = 100 miles

So in the full working week Chris drives 100 miles to work.

Example 5

A water tower contains 2000 gallons of water. Work out the amount of water in the tower in litres.

This time you are using the volume conversion of gallons into litres (1 gallon = 4.5 litres)

So to convert this amount into litres you need to multiply the amount in gallons by 4.5:

2000 × 4.5 = 9000 litres

Therefore, the amount of water in the tower in litres is 9000 lites.

Example 6

A table weighs 110 pounds. Work out the weight of the table in kilograms.

Like example 2 you need to use the weight conversion (1 kilogram = 2.2 pounds).

So to convert the weight from pounds into kilograms you need to divide by 2.2:

110 ÷ 2.2 = 50 kilograms.

So the table weight in kilograms is 50kg.

For some more help on coverting between the two number systems take a look at the following example:
