How to convert microns to mils
1 micron is equal to 0.03937007874 mils, and 1 mil is equal to 25.4 microns. To convert, multiply by the conversion factor:
mils = microns × 0.03937007874
mils = microns ÷ 25.4Example: convert 15 µ to mil: 15 × 0.03937007874 = 0.5905511811 mil.

About the micron
The micron is the older name for the micrometer (one millionth of a meter). It's still common in filtration, semiconductor manufacturing and particle sizes.
Symbol: µ · 1 µ = 0.000001 m · Category: Metric (SI)
About the mil
The mil (or thou) is one thousandth of an inch (25.4 µm). It's used for wire diameters, plastic sheet thickness and circuit board tracks.
