What is a millimeter?

A millimeter (mm) is a metric length unit equal to one thousandth of a meter, commonly used for precise measurements in engineering and science.

What does mil mean in length measurements?

A mil, also known as a thou, is an imperial unit equal to one thousandth of an inch, used mainly in U.S. manufacturing for specifying small thicknesses and tolerances.

Why convert millimeters to mils?

Conversion is essential to translate metric measurements into the imperial system for use in U.S. manufacturing and engineering contexts requiring small-scale precision.

What Is This Tool?

This tool enables users to convert length measurements from millimeters (mm), a metric unit, into mils (mil, thou), an imperial unit commonly used in U.S. manufacturing. It supports precise dimension translations needed for engineering, electronics, and mechanical fabrication.

How to Use This Tool?

Enter the length value in millimeters you want to convert.
Select 'millimeter [mm]' as the from-unit and 'mil [mil, thou]' as the to-unit.
Click the convert button to get the equivalent value in mils.
Review the result to specify dimensions, clearances, or thicknesses in your project.

Key Features

Converts length units from millimeters to mils accurately.
Supports engineering and manufacturing use cases involving small thicknesses and tolerances.
Online, easy-to-use interface accessible via browser.
Clear unit definitions to aid correct specification in various industries.

Examples

2 mm equals 78.7401574804 mils based on the conversion rate.
0.5 mm equals 19.6850393701 mils using the standard conversion formula.

Common Use Cases

Specifying dimensions and tolerances on mechanical and CAD drawings.
Measuring thicknesses of materials like sheet metal, plastic, or coatings.
Defining PCB trace widths, spacing, and drill sizes in electronics manufacturing.
Describing paint or coating thickness in automotive and industrial applications.

Tips & Best Practices

Always confirm the unit system required in your project before conversion.
Use this tool when working across metric and U.S. customary systems to maintain precision.
Double-check converted values when specifying tight tolerances to prevent errors.

Limitations

Rounding errors may occur due to the mil being one thousandth of an inch.
Extra care is needed when converting between metric and imperial units to keep precision.
The mil unit usage outside U.S. customary contexts may cause confusion without clear labeling.
