How to Calculate Fabric GSM without GSM Cutter

Fabric GSM:
GSM means grams per square meter of a knit, woven, or non-woven fabric. It is widely used in the case of knit fabric measurement. GSM plays an important role in the garments manufacturing industry. Finding fabric GSM is a basic and common task for textile engineers or related responsible persons in this sector. In two ways we can find fabric GSM. One is how to find out fabric GSM using GSM Cutter and another is GSM calculation without using GSM Cutter. In this article, I will give a clear concept on the calculation of fabric GSM without using a GSM cutter.

The GSM of fabric is one kind of specification of fabric that is very important for a textile engineer for understanding and production of fabric. ‘GSM’ means ‘Gram per square meter’ that is the weight of fabric in gram per one square meter. By this, we can compare the fabrics in the unit area which are heavier and which is lighter.

How to Calculate Fabric GSM without GSM Cutter

GSM is the weight of 1meter x 1meter fabric. It means 100cm x 100cm = 10,000 sq.cms.

Calculate GSM without using GSM Cutter:

1. For finding out the GSM without using Cutter, we have to follow the below steps:
2. Cut a fabric sample of 10cmX10cm
3. Measure the fabric weight in the manual method
4. Calculate the fabric sample area by multiplying length and width.

We can follow the below formula for getting GSM:

………………………Sample weight x 10,000
Fabric GSM = ………………………………………
………………………..Area of sample fabric

Note: For accuracy, we can take few fabric samples from the different portions of the fabric. Then calculate the average weight of the fabric sample.

Let,

Sample weight (10cmX10cm) = 1.5 gm
Area of sample fabric = 100cm2

Now,

……………………….Sample weight x 10,000
Fabric GSM = ………………………………………….
…………………………Area of sample fabric

….1.5 x 10,000
= …………………..
………..100

= 150

Fabric GSM 150 (ANS).
