Let’s say you measure a ream of paper to be 2 inches thick (about 5.08 cm). Since a ream of paper contains 500 sheets of paper , we divide 2 inches by 500. This will then give us a value of 0.004 inches (about 0.0102 cm), which is the thickness of a single piece of paper.
How is GSM calculated?
How to Calculate Fabric GSM by GSM Cutter:
- Cut the fabric with the GSM cutter (gram per square inch).

- The cut sample is 100 sq. cm. The weight of the cut sample is multiplied by 100.
- The result is the GSM of that particular fabric.
