What is a Mil?

A mil is a tiny unit of length in the imperial system of measurement.

Its most crucial definition is simple: one mil is equal to one-thousandth of an inch (1/1000 or 0.001 inches).

The plural form of the unit is mils.


Where Does the Name 'Mil' Come From?

The name "mil" comes from the Latin word millesimum, which means "thousandth"—a perfect fit for a unit that represents 1/1000th of an inch.

In engineering and manufacturing, especially in the UK, you might also hear a mil referred to as a thou. This nickname helps prevent confusion with metric units, such as the millimeter.


What is a Mil Used For?

The mil measurement is essential in industries where precision is key, even over minimal distances.

To give you some perspective, a human hair is about 2 to 4 mils thick.

This unit is commonly used to specify the thickness or diameter of:

  • Thin materials like plastic bags and foils
  • Coatings, such as layers of paint or plating
  • Paper and cardstock
  • Wires and electrical conductors
  • Manufacturing tolerances for electronic parts, like printed circuit boards (PCBs)

Mil vs. MM: What's the Difference?

It's crucial not to confuse the imperial mil with the metric millimeter (mm). A millimeter is a much larger unit of measurement.

Here's a simple breakdown of the mil vs. mm conversion:

  • 1 mil = 0.0254 mm
  • 1 mm = 39.37 mils

As you can see, one millimeter is nearly 40 times larger than one mil.

It is crucial to specify the units used in technical specifications to avoid significant mistakes.
