• Take and place the sample of fabrics.
  • Cut a circular piece of fabric with the help of a GSM round cutter.
  • By using precise scale weight circular fabric.
  • Record the weight.
  • Now measure the diameter of a sample with a GSM round cutter.
  • The area of a fabric can be calculated by using A = πr²
  • After finding the area, divide the weight by area and you will get the GSM value of the fabric.
