1) Fabric weight is an important characteristic that determines the weight of finished garments. 2) The purpose of fabric weight measurement is to assess the mass per unit area in grams per square meter of a fabric. 3) The apparatus used includes a circular sample cutter that cuts pieces of 100cm^2, a weight balance, and a cutting board. Samples should be cut avoiding the selvedge and ensuring no two pieces contain the same warp and weft yarns. 4) By dividing the total area by the sample area, a factor is obtained to multiply the sample weight to determine the grams per square meter of the full fabric piece.
