The following is a list of definitions relating to conversions between square millimeters and square meters.

A square millimeter is a unit of area in the Metric System. The symbol for square millimeter is mm^{2}. There are 1,000,000 square millimeters in a square meter. A square millimeter is calculated as the area of a square that has 1 millimeter on each side. The International spelling is square millimetre.

A square meter is a unit of area in the Metric System. The symbol for square meter is m^{2}. There are 0.000001 square meters in a square millimeter. A square meter is calculated as the area of a square that has 1 meter on each side. The International spelling is square metre.

Let's take a closer look at the conversion formulas so that you can do these conversions yourself with a calculator or with an old-fashioned pencil and paper.

The formula to convert from mm^{2} to m^{2} is:

m^{2}= mm^{2}÷ 1,000,000

The formula to convert from m^{2} to mm^{2} is:

mm^{2}= m^{2}x 1,000,000

Next, let's look at some examples showing the work and calculations that are involved in converting from square millimeters to square meters (mm^{2} to m^{2}) or converting from square meters to square millimeters (m^{2} to mm^{2}).

Task: Convert 40,000 square millimeters to square meters (show work)Formula:mm^{2}÷ 1,000,000 = m^{2}Calculations:40,000 mm^{2}÷ 1,000,000 = 0.04 m^{2}Result:40,000 mm^{2}is equal to 0.04 m^{2}

Task: Convert 16 square meters to square millimeters (show work)Formula:m^{2}x 1,000,000 = mm^{2}Calculations:16 m^{2}x 1,000,000 = 16,000,000 mm^{2}Result:16 m^{2}is equal to 16,000,000 mm^{2}
