**Square millimetres** (mm² for short) and **square centimetres** (cm² for short) are units of measurement for very small areas. They are converted using a factor of 100, which means that 1 cm² is converted to 100 mm². Conversely, 1 mm² is exactly 0.01 cm².

Square millimetres are the unit of area that corresponds to the size of 1 millimetre by 1 millimetre. Conversely, this means that square centimetres are the unit of area for 1 centimetre by 1 centimetre.

To convert square millimetres to square centimetres, you simply have to divide the number of millimetres by 10. To do this, we must remember that 1 cm = 10 mm. So when converting, you multiply by a factor of 0.1 - or divide by 10.

Let's illustrate this with an example: If you want to calculate 4500 mm2, you have to divide this number by 10 and get 450 cm2 as the result. Another way to do this is to use a calculator. Simply enter the number of millimeters into the calculator and let it show you the result directly.

So to convert square millimetres to square centimetres, all you have to do is either divide the number of millimetres by 10 or multiply it by 0.1 and you have your result!
