In this activity, we will be converting measurements using a conversion graph.

Example

Use the graph to convert 25 cm into inches.

Answer

Find 25 cm on the graph along the y-axis - that's the vertical line.

Move across the graph from 25 cm until you reach the blue diagonal line.

From that point, move straight down from the blue line until you reach the bottom line (the x-axis).

You should have arrived at 10 inches!

So, 25 cm = 10 inches.

Does that make sense?

Let's try some questions on this now.
