how much does a wet bath towel weigh
One way to determine the GSM is to weight the towel and measure the towel length and width. Let's compare, for example, two towels both weighing 1.5 pounds (680 grams) but with different dimensions, as follows: Towel A weighs 1.5 pounds (680 grams) and measures 26 by 52 inches (.66 meters by 1.32 meters). Calculate the surface area by multiplying the length and width in meters: .66 times 1.32 equals .8712 square meters. Divide the weight in grams (680) by .8712 and find that you have a 780 GSM towel.
