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