The weight of a fabric is usually expressed in grams per square meter (g/m²), not in kilograms per meter. The number of meters in a kilogram of fabric therefore depends on the density or weight of the fabric per square meter. For example, 1 kg of a fabric with a density of 200 g/m² corresponds to a length of 5 meters. If the fabric density is higher, the length for 1 kg of fabric will be correspondingly shorter, and vice versa for lower density.
