By means of instruments:Apparatus required
- Round GSM cutter and GSM Pad
- Weighing Balance.
- Cut 5 swatches from the different place of the fabric.
- Weight all test swatches accurately and calculate average weight of swatches.
- Multiply the average weight of swatches by 100 to calculate GSM of the sample fabric. (Normally, the area of round GSM cutter is 1/100 square meters.)
By Using Formula:No need to worry if you don’t have a GSM cutter. You can still measure fabric weight per square meter by using following formula.
