📐 Mil → Inch Converter
Translate mil dimensions into inches for machining and PCB documentation.
Effortlessly convert thousandths-of-an-inch measurements into decimal inches and supporting metric units.
5 mils equals
0.005 in
Millimeters: 0 mm
Micrometers: 127 µm
How to Use This Calculator
Enter mils
Provide the thickness or dimension in mils (0.001").
View inches
The converter divides by 1,000 to display decimal inches.
Check metric equivalents
Millimeter and micrometer outputs help with international specifications.
Formula
Inches = mils ÷ 1,000
Millimeters = mils × 0.0254
Micrometers = mils × 25.4
Use the formula breakdown to confirm the calculation logic or perform the conversion manually if needed.
Full Description
The mil is handy for fine tolerances but most people understand fractional or decimal inches better. This converter keeps your documentation clear by showing the exact inch value along with metric references.
It is frequently used in PCB trace calculations, sheet-metal specs, and coating thickness reports.
Frequently Asked Questions
What is a mil?
A mil (or thou) is one-thousandth of an inch (0.001").
Can I convert inches back to mils?
Yes—multiply inches by 1,000.
Does it support decimals?
Enter decimal mils if needed; the converter works with fractional inputs.
Why include metric outputs?
Many projects require both imperial and metric documentation, so the extra units aid collaboration.
