GSM Calculator

Calculate the Grams per Square Meter (GSM) for a Material

Provided by SolveTech Thickness Gauging

About the Calculation

To calculate the gsm of your material, simply fill out the fields above and select the correct units.  It’s free and easy to use!

This calculation is commonly used for nonwoven materials, paper, plastic and other thin materials.  The most common way to measure GSM is using a scale and a ruler, but there are sometimes other methods needed for industrial processes.

This calculation is based on the equation below and adjusted based on the units selected.

SolveTech's Non-contact Technology for Measuring GSM


Measuring Basis Weight GSM
Measure Basis Weight On or Off-Line

Want to measure the basis weight variability of a material on-line or off-line?

SolveTech’s unique technology can help.

SolveTech Gauging specializes in manufacturing a proprietary thickness gauging technology that can measure the basis weight of non-conductive materials.  It measures the material using the dielectric response, and it does not have any nuclear or x-ray hazards.  Common applications include nonwoven materials and coatings.


Interested in learning how you can scan your material to see its GSM profile?  Contact us here.  Highly accurate and repeatable measurement results that will allow you to see your material variability like never before.


Nonwoven Basis Weight
The profile above was generated using the SolveTech PR2000. A cross web strip was run to determine the variability across the web. The blue line was the first run, and the red line was the second run, and the results have been overlaid to show the repeatability and accuracy.
