🛠️ Micron → Mil Converter
Translate micrometer features into thousandths of an inch.
Designed for PCB design, coating thickness plots, and manufacturing specs that bridge metric microns with imperial mils.
50 µm equals
1.969 mils
Inches: 0.002 in
Millimeters: 0 mm
How to Use This Calculator
Enter microns
Measure the feature in micrometers and enter the value.
View mils
The converter multiplies by 0.0393701 to deliver mils.
Check supporting units
Inches and millimeters provide additional references for manufacturing sheets.
Formula
Mils = Microns × 0.0393701
Inches = Microns × 3.93701 × 10⁻⁵
Millimeters = Microns ÷ 1,000
Use the formula breakdown to confirm the calculation logic or perform the conversion manually if needed.
Full Description
Microns provide the precision needed for electronics and coatings, while mils remain entrenched in legacy documentation. This converter keeps your data aligned with both standards and ensures drawings, fabrication notes, and QA reports remain consistent.
Supplemental inch and millimeter outputs save you from repeated conversions when cross-referencing with design tables.
Frequently Asked Questions
Is micrometer the same as micron?
Yes, they both represent 10⁻⁶ meters.
What tolerance should I expect when rounding?
The converter reports exact values. Round according to your fabrication tolerances.
Does it support negative values?
Negative dimensions are not physical, so negative inputs are disallowed.
Can I convert mils to microns?
Use the mil conversion tool or multiply mils by 25.4 to get microns.
