How to be calculating Fabric GSM without GSM Cutter?

GSM is short form of “Gram per Square Meter”.  GSM is the weight in gram per square meter in fabric. GSM is a very important parameter of specified a certain quality of knitted fabric. The production calculated in “Weight” for knitting. GSM Cutter is very popular & easy usable instrument in all knit factory. But, now we learn How to be calculating Fabric GSM without GSM Cutter.

Suppose,

We have 4*2 Yds fabric which that weight is 2 Kg.

 

So, we know,

1 inch = 2.54 cm

36 inch = 36*2.54 = 91.44 cm

2 yards = 91.44 * 2 = 182.88 cm / 100 = 1.8288 mm

4 yards = 91.44 * 4 = 365.76 cm / 100 = 3.6576 mm

Total Area = 4 yards * 2 yards = 1.8288 * 3.6676 = 6.68901888 m2

Now, 2 kg = 2 * 1000 gm = 2000 gm

So,

6.68901888 m2 = 2000 gm

GSM = 2000 / 6.68901888 = 298.997 ~ 299
