How do you calculate fabrics yards from gsm?

Answer 1

Easy formula for calculate gsm as below,

GSM= (EPI/Warp count*1.1)+(PPI/Weft count*1.04)*23.5

Suppose: Fabric is 20x20/60x60

Calculate:

(60/20x1.1)+(60/20x1.04)x23.5 =(3.3+3.12)x23.5=6.42x23.5=150.87

So, GSM is 150.87maximum

Hopefully you get it.

Answer 2

To determine approximate GSM (grams per square meters) of a given fabric, you can use following formula. One of my colleagues used to use this formula in testing lab. In case different counts of warp thread or weft thread is used then this formula will not give you correct GSM. It is also known as conversion formula from fabric construction to fabric weight.

Fabric GSM = (EPI/warp count + PPI/Weft count) x (100+crimp %) X 0.2327

For example, construction of a fabric is 40 X40 /120 X 60 and warp and weft crimp is 6%. Then GSM of this fabric will be,

GSM = (120/40 + 60/40) X (100+6%) X 0.2327

GSM =104.77

I found others to use this formula with different multiplying factors.

Fabric GSM= ((EPI/warp count X 1.1) + (PPI/weft count x 1.04)) x 23.5 By Dharmi

Where 1.1 and 1.04 are warp and weft crimp factors respectively.
