GSM Formula: How to Calculate the GSM of Paper and Fabric
GSM stands for grams per square meter, which is a unit of measurement for the weight and thickness of paper and fabric. GSM is also known as gram weight or basis weight. The higher the GSM, the heavier and thicker the paper or fabric is. The lower the GSM, the lighter and thinner the paper or fabric is. GSM is an important parameter for determining the quality and suitability of paper and fabric for various purposes, such as printing, packaging, clothing, and more.
GSM Formula
The GSM formula is a simple mathematical equation that can be used to calculate the GSM of paper and fabric. The GSM formula is:
GSM = (Weight of paper or fabric in grams) / (Area of paper or fabric in square meters)
For example, if a sheet of paper weighs 10 grams and has an area of 0.2 square meters, then the GSM of the paper is:
GSM = (10 grams) / (0.2 square meters) = 50 grams per square meter
Alternatively, the GSM formula can be rearranged to calculate the weight or the area of paper or fabric, given the GSM and the other variable. For example, if a piece of fabric has a GSM of 100 and an area of 0.5 square meters, then the weight of the fabric is:
Weight = (GSM) x (Area) = (100 grams per square meter) x (0.5 square meters) = 50 grams
Similarly, if a roll of paper has a GSM of 80 and a weight of 400 grams, then the area of the paper is:
Area = (Weight) / (GSM) = (400 grams) / (80 grams per square meter) = 5 square meters
GSM Calculation Formula
The GSM calculation formula is a more advanced and accurate method to calculate the GSM of paper and fabric, especially when the paper or fabric is composed of multiple layers or different materials. The GSM calculation formula is:
GSM = (Weight of paper or fabric in grams) / (Length of paper or fabric in meters) x (Width of paper or fabric in meters)
For example, if a piece of fabric weighs 150 grams and has a length of 2 meters and a width of 1 meter, then the GSM of the fabric is:
GSM = (150 grams) / (2 meters) x (1 meter) = 75 grams per square meter
The GSM calculation formula can also be used to calculate the weight or the length or the width of paper or fabric, given the GSM and the other two variables. For example, if a sheet of paper has a GSM of 60 and a length of 1.5 meters and a width of 1 meter, then the weight of the paper is:
Weight = (GSM) x (Length) x (Width) = (60 grams per square meter) x (1.5 meters) x (1 meter) = 90 grams
Similarly, if a roll of fabric has a GSM of 120 and a weight of 600 grams and a width of 1.2 meters, then the length of the fabric is:
Length = (Weight) / (GSM) / (Width) = (600 grams) / (120 grams per square meter) / (1.2 meters) = 4.17 meters
