Given the linear density and weight the yarn length can be calculated; for example: l/m = 1693 × l m /Nec × m/kg, where l/m is the yarn length in metres, l m /Nec is the English cotton count and m/kg is the yarn weight in kilograms. The following length units are defined. Bundle: usually 10 lb (4.5 kg)
