HOW TO CALCULATE PAPER GSM?

To calculate the GSM (grams per square meter) of paper, you can use the following formula: GSM = (Weight of the paper in grams / Area of the paper in square meters). First, weigh a known size of the paper (e.g., A4 size) and convert its dimensions to square meters. Then, divide the weight by the area to get the GSM value. For example, if a sheet weighs 4.5 grams and measures 0.06237 square meters (A4 size), the GSM would be approximately 72.2.
