How to Convert Millimeters to Meter Squared

You can convert millimeters to meters squared if you have the measurements of an area in millimeters. Millimeters and meters squared are both units that are used in the metric system of measurement. One thousand millimeters are equivalent to one meter. Because millimeters are a measure of distance, and meters squared are a measure of area, you must have the measurements of the length and width of an area to convert millimeters to meters squared.

Things You'll Need

• Metric ruler
• Writing utensil (e.g. pencil)
• Paper
• Calculator (optional)

Instructions

1. Measure the length of the area in millimeters.

2. Measure the width of the area in millimeters.

3. Multiply the measurements from Step 1 and Step 2 together, and record the result.

4. Divide the result from Step 3 by 1000. The result is the number of meters squared.
