To calculate the weight of paper using the paper’s GSM (grams per square meter) measurement, you need to know the size of the paper and the GSM value. Here’s how you can calculate the weight:
Determine the Paper Size: Measure the dimensions of the paper in either inches or centimeters. You need to know the length and width of the paper.
Convert the Paper Size to Square Meters: Convert the dimensions of the paper to square meters. If the dimensions are in inches, divide the length and width by 39.37 to convert them to meters. If the dimensions are in centimeters, divide them by 100 to convert them to meters. Multiply the length by the width to obtain the paper area in square meters.
Calculate the Weight: Multiply the paper area in square meters by the GSM value to obtain the weight of the paper. The result will be in grams. If you prefer the weight in pounds, you can convert grams to pounds by dividing the weight in grams by 453.59237 (since there are 453.59237 grams in a pound).
Here’s an example calculation:
Let’s say you have a piece of paper with dimensions 21.6 cm x 27.9 cm and a GSM value of 80.
Convert the Paper Size to Square Meters: Length = 21.6 cm / 100 = 0.216 meters Width = 27.9 cm / 100 = 0.279 meters Paper Area = 0.216 meters x 0.279 meters = 0.060264 square meters
Calculate the Weight: Weight = 0.060264 square meters x 80 GSM = 4.82032 grams Weight in Pounds = 4.82032 grams / 453.59237 = 0.01063 pounds (approximately)
Therefore, the weight of the paper would be approximately 4.82032 grams or 0.01063 pounds.
Remember, this calculation method assumes a single sheet of paper. If you are calculating the weight of a ream (500 sheets) or a specific quantity of paper, you’ll need to adjust the calculation accordingly by dividing or multiplying as necessary.
