How to Convert English Cotton Count to Tex
- tex = 590.5412474 ÷ Ne
- Ne = 590.5412474 ÷ tex
- Example: convert 30 Ne to tex: 590.5412474 ÷ 30 = 19.68470825 tex
Formula
tex = 590.5412474482 ÷ Ne
Derivation from SI units:
- Ne = number of 840-yard hanks per pound, so tex = 0.45359237 kg ÷ (840 × 0.9144 m) × 10⁶ ÷ Ne = 590.5412 ÷ Ne
- 1 tex = 1 g per 1000 m = 10⁻⁶ kg/m (exact)
- Solving for tex: tex = 590.5412474482 ÷ Ne (a higher Ne means a lower tex)
Both units are defined exactly, so the factor is exact. English Cotton Count definition: English cotton count; Tex definition: tex.
Worked examples
- A 30 Ne cotton yarn is 19.68470825 tex.
590.5412474 ÷ 30 = 19.68470825 tex - A 40 Ne combed yarn is 14.76353119 tex.
590.5412474 ÷ 40 = 14.76353119 tex

Frequently asked questions
What is 30s count in tex?
30 Ne (30s) = 19.68470825 tex.
What is the formula for English cotton count to tex?
tex = 590.5412474 ÷ Ne. The two systems are inversely related, so divide the constant by the value; do not multiply. For example, 590.5412474 ÷ 30 = 19.68470825 tex.
Why does a higher Ne give a lower tex?
English Cotton Count counts length per unit mass (an indirect system), while tex counts mass per unit length (a direct system). A finer yarn has a higher indirect number and a lower direct number.
Is the Ne to tex conversion exact?
Yes. Both units are defined exactly, so the ratio is exact; its decimal form does not terminate and is shown here to 10 significant figures (more with the precision selector).
