To convert from Mil (mil) to Micrometer (μm), use the following formula:
With is the ratio between the base units Meter (m) and Foot (ft).
Let's convert 5 Mil (mil) to Micrometer (μm).
Using the formula:
Therefore, 5 Mil (mil) is equal to Micrometer (μm).

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.
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.
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:
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:
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.
A micrometer (μm), commonly referred to as a micron, is a unit of length in the metric system.
It is extremely small, equal to one millionth of a meter (10-6 m).
The micrometer may be tiny, but it's indispensable wherever extreme precision is required. Here are some examples of how it's used across different industries:
Electronics manufacturing: Parts like transistors, traces, and other microchip features are measured in micrometers. Modern CPUs and memory chips depend on manufacturing at these microscopic scales.
Aerospace engineering: Components are machined to micrometer tolerances, ensuring they fit and perform reliably under extreme stress and temperature conditions.
Medical devices: Stents, catheters, and many surgical tools must be produced with micrometer-level accuracy to ensure patient safety and proper function.
Textiles: Fiber diameters—such as wool, silk, and synthetic fibers—are measured in micrometers to assess softness, strength, and the best uses for each material.
Small unit, significant impact: micrometer-level precision underpins quality, safety, and performance across many fields.
It can be hard to grasp just how small a micrometer is.
To put this micrometer size comparison into perspective, consider these examples:
These comparisons highlight the incredible microscopic scale the micrometer represents, far smaller than anything the naked eye can perceive.
Yes, they are the same.
The official name for this unit in the International System of Units (SI) is the micrometer; however, it is often still referred to by its older name, the micron.
The term "micron" was officially retired in 1967 to standardize terminology and prevent confusion. Nonetheless, it remains commonly used in various industries and scientific contexts due to habit.
Therefore, when you encounter a measurement in microns, it is equivalent to a micrometer (1×10-6 meters).
