### How do you calculate square metres?

First, you will need to think about the area you are trying to measure.

Most properties have multiple rooms, usually square or rectangular.

If so, you must split up these areas individually, calculate for each area separately and then add up all the results at the end.

Measure each area and enter your results into the calculator. Ideally, you should use a measuring tape to do this. Make sure to round up your measurements as necessary.  #### For a rectangle or square:

Simply measure the length and the width. #### For a circle:

You will need to measure the middle of the circle by dividing it in half. This is called the diameter. Then half the diameter to get the radius, which you then input into the calculator above.
