    Calculate fabric GSM ;

   

     Total weight of fabric = 15 kg

   Length of fabric = 30 meters

Weight of fabric in open from = 60 inch or 1.52 meter

Fabric area = length ×weight

                       = 30×1.52

                        =  45.6 mater square .

Now ,

         Fabric weight = 15 kg or 15000 grm

   So weight of one square mater  =  15000÷45.6

                                                            = 328 GSM
