GSM Calculator

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


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

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

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.



This calculation is commonly used for nonwoven materials, paper, plastic and other thin materials.  If you have any questions, please feel free to contact us.  We are measurement experts and can offer precise and custom gauging solutions.

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

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.
