How to Convert English Cotton Count to Denier
- den = 5314.871227 ÷ Ne
- Ne = 5314.871227 ÷ den
- Example: convert 30 Ne to den: 5314.871227 ÷ 30 = 177.1623742 den
Formula
den = 5314.871227034 ÷ 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 den = 1 g per 9000 m = 1/9 tex ≈ 1.111 × 10⁻⁷ kg/m (exact)
- Solving for den: den = 5314.871227034 ÷ Ne (a higher Ne means a lower den)
Both units are defined exactly, so the factor is exact. English Cotton Count definition: English cotton count; Denier definition: denier.
Worked examples
- A 30 Ne yarn is 177.1623742 den.
5314.871227 ÷ 30 = 177.1623742 den - A fine 60 Ne yarn is 88.58118712 den.
5314.871227 ÷ 60 = 88.58118712 den

Frequently asked questions
Which denier matches a 40s cotton yarn?
40 Ne = 132.8717807 den, using denier = 5314.87 ÷ Ne.
What is the formula for English cotton count to denier?
den = 5314.871227 ÷ Ne. The two systems are inversely related, so divide the constant by the value; do not multiply. For example, 5314.871227 ÷ 30 = 177.1623742 den.
Why does a higher Ne give a lower den?
English Cotton Count counts length per unit mass (an indirect system), while denier 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 den 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).
