tex: Grams per 1,000 metres of yarn. Tex is a direct measure of linear density.
den (denier): Grams per 9,000 metres of yarn. Den is a direct measure of linear density.
dtex (deci-tex): Grams per 10,000 metres of yarn. Dtex is a direct measure of linear density.
gr/yard: Grains per yard of yarn. Gr/yard is a direct measure of linear density, but is rarely used in the modern textile industry. ( 1 Grain = 0.0647 Gram)
NeC or Ne (English Cotton Count): The number of 840 yd lengths per pound.
NeK or NeW (Worsted Count): The number of 560 yd lengths per 1 lb of yarn. NeK is an indirect measure of linear density.NeK is also referred to as the spinning count.
NeL or Lea (Linen Count): The number of 300 yd lengths per 1 lb of yarn. NeL is an indirect measure of linear density.
NeS (Woollen Count or Yorkshire Skeins Woollen): The number of 256 yd lengths per 1 lb of yarn. NeS is an indirect measure of linear density. One of the best known of the many different woolen yarn counts.
