🔬 Micrometer Converter

Switch micrometer lengths into nanometers, millimeters, inches, and mils.

Ideal for PCB layouts, precision machining, and microscopy where feature sizes are recorded in micrometers but tooling expects other units.

Nanometers (nm)1,250,000
Millimeters (mm)1
Centimeters (cm)0.13
Meters (m)0.0013
Inches (in)0.049
Mils (thou)49.213

How to Use This Calculator

1

Enter micrometers

Type the feature size measured in µm.

2

Review conversions

See the corresponding metric, imperial, and PCB-friendly mil units.

3

Use in fabrication

Apply the values in CAD programs, machine setups, or tolerance tables.

Formula

Nanometers = Micrometers × 1,000

Millimeters = Micrometers ÷ 1,000

Inches = Micrometers × 3.93701 × 10⁻⁵

Mils = Inches × 1,000

Use the formula breakdown to confirm the calculation logic or perform the conversion manually if needed.

Full Description

The micrometer is a standard unit for thin films, trace widths, and precision tolerances. Converting it to familiar units like mils or inches ensures compatibility with tooling that still relies on imperial measures.

Metric conversions keep laboratory data aligned with international standards, while imperial conversions support legacy documentation.

Frequently Asked Questions

Is a micron the same as a micrometer?

Yes. Both terms refer to 10⁻⁶ meters.

What is a mil?

A mil is a thousandth of an inch (0.001 in), commonly used in PCB fabrication.

Can I convert mils back to micrometers?

Use the mil conversion tool or multiply mils by 25.4 to obtain micrometers.

Does it support nanometers?

Yes—nanometers are listed so you can scale dimensions for semiconductor work.
