Convert square millimeters (mm²) to hectares (ha) with formulas, examples, and conversion tables.
To convert 1 square millimeters to hectares, we divide by 1e+10 because one hectare equals exactly 1e+10 square millimeters.
Since there are 1e+10 square millimeters in every hectare, we divide our value by this factor:
So 1 square millimeters = 1e-10 hectares.
To convert square millimeters to hectares, divide the value by 1e+10.
1 hectare = 1e+10 square millimeters
