mil to mm Conversion

The mil to mm conversion can be a crucial task in engineering, manufacturing, or any field that requires precise measurements. Luckily, Omni's easy-to-use mil to mm conversion tool simplifies this process. Whether you need to convert measurements from mils to millimeters or vice versa, this tool provides accurate results in the blink of an eye.

Keep reading to discover what a mil is and learn how to convert mm to mils yourself.

A mil is an imperial unit of measure equal to one-thousandth of an inch (0.001 inches) or 25.4 micrometers (0.0254 millimeters). It's derived from the inch and is also known as a "thou" (or thousandth).

The mil is commonly used in manufacturing and engineering to measure the thickness of materials and manufacturing tolerances.

Although our tool provides quick and accurate conversions between mils and millimeters, it's always helpful to understand how the conversion works. This comes down to knowing the conversion factor between these two units from two different systems: the imperial and the metric.

Let's start by mentioning that $1 \rm{\ mil}$ is equal to one thousandth of an inch:

Knowing the conversion between inches and millimeters can help us get the mil to mm conversion factor. We can recall that $1 \rm{ \ inch}$ is equal to $25.4 \rm{\ mm}$:

Thus, we get that the mil to mm conversion factor is:

To convert mils to millimeters, simply multiply the measurement in mils by the conversion factor. For instance, if you want to convert $7 \rm{ \ mils \ to \ millimeters}$, you would multiply $7$ by $0.0254$:

Suppose you want to convert 12 mil to mm. What do you do? Ask a friend for help? Calculate it yourself? Or use our tool? 😅 If you choose to go with the latter, here's what you need to do:

1. In the first row, enter the mil measurement, 12 mil in our case.

2. Voila! The calculator will display the result in mm. For our example, this is 0.3048 mm.

It's equal to 0.127 mm. We used the mil-to-mm conversion factor of 1 mil = 0.0254 mm to obtain this value. Then by multiplying the measurement we want to convert, 5 mil, by this conversion factor, we get the previously mentioned result:

5 mil × (0.0254 mm / 1 mil) = 0.127 mm

To convert from mm to mils, follow these steps:

1. Identify the measure in mm that you want to convert.

2. Use the mil to mm conversion factor:

   1 mil = 0.0254 mm

3. Divide your measurement in mm by 0.0254 mm.

4. The result is your measurement in mils.
