## Square millimeters to square microns conversion factor and formulas

Formula

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

### Multiplication

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

### Division

Alternatively we can divide 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 millimeters to square microns, divide square millimeters by 0.
The formula is expressed as:
mm2 ÷ 0 = µ2
