## Square microns to square millimeters conversion factor and formulas

Formula

The conversion factor between square microns and square millimeters is 1,000,000. This represents the ratio of square microns per one square millimeter. To calculate the value in square millimeters, we can either divide by the conversion factor or multiply by its inverse.

### Division

To convert from square microns to square millimeters, divide square microns by 1,000,000.
The formula is expressed as:
µ2 ÷ 1,000,000 = mm2

### Multiplication

Alternatively we can multiply by the inverse conversion factor to get the same result.
The inverse of 1,000,000 is 1/1,000,000 or 0. To convert from square microns to square millimeters, multiply square microns by 0.
The formula is expressed as:
µ2 × 0 = mm2
