The commonly used calculation formulas for textiles are divided into two types: the fixed length calculation formula and the fixed weight calculation formula.

1. Formula for calculating the fixed length system:

(1), denier (D): D = g / L * 9000 where g is the weight of the wire (grams), L is the length of the wire (meters)

(2), tex (number) [tex (H)]: tex = g / L * 1000 where g is the weight (gram) of the yarn (or silk), L is the length of the yarn (or silk) (meter )

(3), Dtex (dtex): dtex=g/L*9000 where g is the weight of the wire (g), L is the length of the wire (m)

2. Formula for calculating the weight system:

(1), metric count (N): N = L / G where G is the weight (gram) of the yarn (or silk), L is the length of the yarn (or silk) (m)

(2), the British count (S): S = L / (G * 840) where G is the weight of the wire (in pounds), L is the length of the wire (code)
