## How do you calculate yarn count in GSM?

‘GSM’ means ‘Gram per square meter’ that is the weight of fabric in gram per one square meter.

Relation Among Yarn Count, Machine Gauge & Fabric GSM:

G.S.M. Count Gauge
140 30 s 24 gg
150 28 s 24 gg
160 26 s 24 gg
170 24 s 24 gg

## How is GSM calculated?

How to Calculate Fabric GSM by GSM Cutter:

1. Cut the fabric with the GSM cutter (gram per square inch).
2. Weight the fabric with the electric balance.
3. The cut sample is 100 sq. cm. The weight of the cut sample is multiplied by 100.
4. The result is the GSM of that particular fabric.

## What is GSM count?

It refers to the number of horizontal and vertical threads per square inch. Therefore, the higher the thread count, the better wear-tear and softer the sheet. While a high thread count is an important factor, the cotton type used is more significant.

## Is 170 GSM cotton good?

That will depend on what your needs are. Fabric weight is in almost all cases is a definition of the thickness of the garment itself. If you want a heavy t-shirt then a 180-200gsm item is generally at the very top end of a t-shirt weight, but if you want a nice lightweight summer t-shirt a 130-150 is also great.

## Is 180 GSM cotton good?

Even though a higher GSM fabric offers higher durability, but when it comes to T-shirts these heavy fabrics are not wearable and preferable during summer weather. T-shirts chosen by us have a GSM strength of 180.

## How do you convert GSM to thickness?

A rule-of-thumb then is to multiply specific density values by 1000 to obtain the weight of a sheet that is one millimeter in thickness. As an example, the specific density of PP ranges from 0.855 g/cc to 0.946 g/cc. A one millimeter thick layer of PP would then have an areal weight between 855 gsm and 946 gsm.

## Why is GSM important?

The most obvious advantage of GSM is its widespread use throughout the world. According to Gsmworld.com, GSM has a harmonized spectrum, which means that even though different countries may operate on different frequency bands, users can transfer seamlessly between networks and keep the same number.
