How to weight fabric weight GSM when looking for clothing?

Today let's talk about how to weight the fabric GSM (also known as gm/2) = grams per square meter and is the metric measurement of the weight of a fabric.

First use below GSM machine one circle piece fabric from hoodies,sweatshirt,polo,t shirt,yoga

Then weight the cut circle fabric as below(e.g.200gsm)

Metric measurements are generally the most common place but some clothing items are still marked in Imperial weights (OZ or oz/yd2 = ounces per yard squared)

The important thing to state here is that all of the terms above are measurements of weight, specifically the fabric weight when talking clothing.

You can convert OZ & GSM by 1OZ=1.09*1.09*28.35GSM
e.g. when talk about zip up hoodies in 8.5OZ: 8.5oz x 1.09*1.09*28.35= 286.30 gsm

When talk about short sleeve men's v neck t shirt in 5.4OZ: 5.4.6oz*1.09*1.09*28.35=181.89gsm

When talk about custom polo shirts in 200gsm: the convert ways same above:200÷(1.09*1.09*28.35)=6oz

and so on.
