Square millimeter to square meters Conversion
1 square millimeter (mm²) is equal to 0.000001 square meters (meters²).
1 mm² = 0.000001 meters²
or
1 meters² = 1000000 mm²
Formula
To convert a area from square millimeter (mm²) to square meters (meters²), divide the area in square millimeter by 1000000
a(meters²) = a(mm²) / 1000000
Examples:
Convert 100 square millimeter to square meters:
a(meters²) = 100mm² / 1000000 = 0.0001 meters²
