How to Convert Worsted Count to English Cotton Count
- 1 Nw = 0.6666666667 Ne
- 1 Ne = 1.5 Nw
- Example: convert 30 Nw to Ne: 30 Nw = 30 × 0.6666666667 Ne = 20 Ne
Formula
Ne = Nw × 0.6666666666667
or Ne = Nw ÷ 1.5
Derivation from SI units:
- Nw = number of 560-yard hanks per pound, so tex = 885.8119 ÷ Nw
- Ne = number of 840-yard hanks per pound, so tex = 0.45359237 kg ÷ (840 × 0.9144 m) × 10⁶ ÷ Ne = 590.5412 ÷ Ne
- 1 Nw = 0.0008858118711724 kg/m ÷ 0.0005905412474482 kg/m per Ne = 0.6666666666667 Ne
Both units are defined exactly, so the factor is exact. Worsted Count definition: worsted count; English Cotton Count definition: English cotton count.
Worked examples
- A 30 Nw yarn is 20 Ne.
30 Nw × 0.6666666667 = 20 Ne - A 60 Nw yarn is 40 Ne.
60 Nw × 0.6666666667 = 40 Ne

Frequently asked questions
Why is worsted count 1.5 times cotton count?
The worsted hank is 560 yd and the cotton hank 840 yd, so Ne = Nw × 560/840 = Nw × 2/3.
How many English cotton count are in 1 worsted count?
1 Nw = 0.6666666667 Ne.
How do I convert worsted count to English cotton count?
