## Conversion graphs

Conversion graphs show us how two different units are related to each other, for example two types of currency. You could also use them to work out the relationship between different types of weight, temperature or length.

Look at this example of a graph that we could use to convert between two different currencies - Euros (€) and British pounds (£).

Imagine you wanted to convert £20 into Euros. You can use the conversion graph to do this easily.

1. Find £20 on the British pounds axis.

2. Read up to find where it meets the diagonal conversion line.

3. Read across to the Euro axis to find the converted value.

From the graph you can see that £20 converts into €22.50.

Watch this video from Sparx to learn more about solving different problems using conversion graphs. To see a short recap and further example of the learning points you have covered so far, watch the video from the beginning. If you are ready to carry on and progress your learning, begin watching at 1:25.

Please pause the video as needed, so you can stop and work out the different problems for yourself.
