Plastic Gauge Thickness Chart | Plastic Film/Sheets Thickness Gauge Conversion & Calculation | CNCLATHING


When it comes to the application of the plastic CNC products or material, the thickness comes into consideration. If you can’t find a way to convert plastic film thickness gauge between Mil, MM, and other units, please check the plastic gauge thickness chart and calculation formula at the following.

What is Plastic Gauge Thickness?

The thickness of plastic film or sheet is often described as Gauge, or expressed in Mil, which is equal to a thousand of an inch. Other ways to represent plastic thickness are including Micron and Millimeter. To master and express the thickness of plastic materials correctly in any places and times, there is a plastic gauge thickness chart to help you move between these units. For beginners in designing and production, lots of varieties of plastic measurement may be confusing, the conversion chart can ensure them find the proper thickness of the material.

Plastic Gauge Thickness Chart - Plastic Film/Sheet Thickness Gauge Conversion

The conversion relationship between these thickness units is: a Mil is 1000 times of an inch, the Gauge is (100) x (Mils), To go from Mils to Microns, you multiply mils x 25.4. So the calculation formulas for plastic gauge are as below.

Mil = 1000 x Inch

Micron = Mil x 25.4

Micron = Gauge x 0.254

Gauge = 100 x Mil

Gauge = Micron x 3.937

You can also choose the Plastic film thickness calculator to get the result faster. 

Here is the plastic gauge thickness conversion chart, you can check some data directly. Plastic gauge is different from wire gauge for plastic gauge measurement, the larger the gauge, the thicker the film. 


1. Gauge is usually reserved for thicknesses below 1 mil. 

2. Mil is a US unit of measurement and Micron (um or Micrometer) is a metric system measurement of thickness.

3. Microns measurements are usually rounded to the nearest whole integer. For example, 7.62 microns is usually expressed in 7.6.

4. Mil to Micron conversion is usually the most important conversion to make when working with flexible barrier plastics.
