Jersey gsm (grams per square metre)
Based on a.c.'s description of their medium weight fabric, which they say is 9.8 ounces per linear yard. Their fabric is 56" wide.
Or 277.83 grams per linear yard
"A linear yard of fabric is a length of fabric that is a yard long. Linear yards only measure length and do not account for the width of the fabric."
Or 277.83 grams per 56" x 36"
Or 277.83 grams per 142.24cm x 91.44cm
Or 277.83 grams per 1.4224m x 0.9144m
Or 277.83 grams per 1.30064256 m^2
Or 213.609803 grams per m^2
Therefore a.c. medium weight fabric = 213gsm
A.C. double layer = 426gsm
160gsm
Single layer = 160gsm
Double layer = 320gsm
Triple layer = 480gsm
