How to Measure Fabric weight of Big quantity
To know the fabric’s weight
For measuring fabric weight in large quantity we can follow the following way which now I am going to present for you. Wish it will be helpful for you who are related to textile. After reading this article you will have a proper idea of how to measure the fabric weight of big quantity.
Usually, we measure GSM (Gram per square meter) by GSM cutter.
 We can get GSM by fabric construction also. Let’s try to get GSM of the following construction:
(20 × 16/128 × 60) twill.
We know,
GSM  = {(EPI/Warp count) + (PPI/ Weft count)} × 25.64 
Here , EPI  = 128 
PPI  = 60 
Warp count  = 20 
Weft count  = 16 
So GSM will be = {(128/20) + (60/ 16)} × 25.64
=260 GSM
 Then you can get GLM (Grams per linear meter) via GSM.
GLM  = ( GSM × fabric width)/39.37 
When 

GSM  = 260 
Width  = 58 
GLM  = (260 × 58)/39.37 
=383 
So 500meter fabrics total weight = GLM × Fabric quantity.
= (383 × 500 m) (here fabric quantity = 500m)  
=191500 grams  
=191500/1000 Kg.  
=191.5 kg. 
So, this is the way how we can measure fabric weight by the known GSM of this fabric. If you have any questions related to this post never hesitate to ask me.
How to Measure Fabric Weight of Big Quantity
Very good
Let me clear … where come from 25.64
Sir i want to know how to find denier of yarn from gsm of woven fabric.
(20 × 16+70D/128 × 60)58″ twill.plz clear this.
Dear Sir, We refer your Glm .It is ok but Gsm our formula not match
I think ours is ok
What is 25.64 and where it comes from
25.64 is a part of formula
25.64 where it come
Is 25. 64 constant to calculate GLM?
Yes it is Constant
The fabric width used in the example is in inches or centimeters?
Easy one is;
GSM X Fabric Width X 0.0254
260 X 58 X 0.0254
= 383
Thanks for sharing easy solution
Hello sir I m hitesh from ahmedabad i m little confused sir ..all clear epi ppi warp weft then gsm then gsm to glm ok but I don’t know in gsm 25.64 where come and glm 39.37 where come so please sir clear this me ..thank you 8154897949 it’s my what’s app number please send me answer ..
Sir kya hum hum seedha he warp k glm or weft ka glm nikaal sakta hai. To sir pls ek example solve kar k bhejna. umesh 66017 @gmail.com per.
how to convert glm to count construction?
Can you kindly tell me in GLM calculation, why are we dividing by 39.37 ?
please explain this formula.
HOW TO CALCULATE GLM AND GSM.
WITH EXAMPLE OF GSM AND GLM AND FORMULA OF GSM AND GLM
GSM = {(EPI/Warp count) + (PPI/ Weft count)} × 25.64
Here , EPI= 128, PPI = 60, Warp count = 20, Weft count= 16,
So GSM will be = {(128/20) + (60/ 16)} × 25.64 =260 GSM
why we multiply by 25.64
Why are we dividing by 39.37, where ti comes from and same 25.64 is come from didn’t get this
