How to Convert English Cotton Count to Kilotex
- ktex = 0.5905412474 ÷ Ne
- Ne = 0.5905412474 ÷ ktex
- Example: convert 15 Ne to ktex: 0.5905412474 ÷ 15 = 0.0393694165 ktex
Formula
ktex = 0.5905412474482 ÷ 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 ktex = 1 g per metre = 1000 tex = 10⁻³ kg/m (exact)
- Solving for ktex: ktex = 0.5905412474482 ÷ Ne (a higher Ne means a lower ktex)
Both units are defined exactly, so the factor is exact. English Cotton Count definition: English cotton count; Kilotex definition: kilotex.
Worked examples
- A reading of 24 Ne converts to 0.02460588531 ktex.
0.5905412474 ÷ 24 = 0.02460588531 ktex - A value of 50 Ne is 0.01181082495 ktex.
0.5905412474 ÷ 50 = 0.01181082495 ktex

Where it's used
English Cotton Count are used for cotton and blended spun yarns (20s, 30s, 40s), while kilotex appear in card and draw-frame sliver (about 3–5 ktex). Both measure yarn count (linear density of yarns and fibres), but one system is the inverse of the other, so a fixed constant is divided by the value.

Frequently asked questions
What is the formula for English cotton count to kilotex?
ktex = 0.5905412474 ÷ Ne. The two systems are inversely related, so divide the constant by the value; do not multiply. For example, 0.5905412474 ÷ 15 = 0.0393694165 ktex.
Why does a higher Ne give a lower ktex?
English Cotton Count counts length per unit mass (an indirect system), while kilotex 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 ktex 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).
