The metric system of weights and measures is used by most industrialized countries around the world, although the United States still uses the Imperial system. The metric system uses meters and centimeters to measure length, while the Imperial system uses feet and inches. When it comes to area, the metric units are meters squared, or square meters, and centimeters squared, or square centimeters, which are actually completely different types of units than meters and centimeters. Those nonsquared centimeters measure width, length and height, while square meters measure area. While you can't convert centimeters (cm) to meters squared, you can use centimeters as the basis for a square-meter measurement.
Find Your Dimensions in Centimeters
Measure the area's dimensions in centimeters. For example, you may have a square area with sides measuring 400 centimeters each.
Convert Centimeters to Meters
Convert your dimensions to meters by diving by 100. In this case, work out 400 ÷ 100 = 4. The sides of your area measure 4 meters each.
Find the Square Meters
Multiply width by height to get the area in square meters. In this case, the width and height are the same (4 meters) so work out 4 × 4 = 16. The area is 16 meters squared, or 16 m2.
TL;DR (Too Long; Didn't Read)
If you have a measurement in centimeters squared, you can convert it to meters squared by dividing it by 10,000. For example, if your measurement is 800 cm2, work out 800 ÷ 10,000 = 0.08. The equivalent is 0.08 meters squared, or 0.08 m2. However, remember centimeters and centimeters squared are completely different types of measurement units.
