Calculate Film Thickness/Gauge By Weight for Plastic Film

Precision Thickness Gauging
Precision Thickness Gauging

The calculator below calculates the theoretical thickness of plastic film using the equation (volume) x (density) = (weight).   This calculator can be used to calculate the average  thickness of plastic film or the thickness of other materials NIST traceably.  Learn more in our article “How to Measure Plastic Film”.

SolveTech, Inc.  manufactures high precision gauging systems using a proprietary capacitance technology.  If you are interested in measuring thickness in the lab, check out our PR2000 Precision Profiler.(Complies with new ASTM Standard D8136)  For on-line applications, see our product page here

Note: A mil is a common unit of thickness measurement for plastic film and is equal to 0.001 inches. For plastic film it is also commonly called gauge, and 0.01 mil = 1 gauge = 0.254 microns.  Therefore, 1 mil = 25.4 microns.

How To Measure Plastic Film

This calculator uses the following concept to calculate plastic film thickness and uses the proper conversion factors for the units used.  This is also known as the cut and weigh method for obtaining the average thickness of plastic film.

The cut and weigh method is often used because it provides a very sound  average material thickness calculation.  However, it is dependent upon knowing your material density.  If you don’t know your material density, it can be measured using a gas pycnometer.  SolveTech offers this as a service to our customers.
