- 1 Ne = 3.28125 NY
- 1 NY = 0.3047619048 Ne
- Example: convert 15 Ne to NY: 15 Ne = 15 × 3.28125 NY = 49.21875 NY
Formula
NY = Ne × 3.28125
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
- Yorkshire woollen count = number of 256-yard skeins per pound, so tex = 1937.7 ÷ count
- 1 Ne = 0.0005905412474482 kg/m ÷ 0.00193771346819 kg/m per NY = 3.28125 NY
Both units are defined exactly, so the factor is exact. English Cotton Count definition: English cotton count; Yorkshire Woollen Count definition: Yorkshire woollen count.
Worked examples
- A reading of 24 Ne converts to 78.75 NY.
24 Ne × 3.28125 = 78.75 NY - A value of 50 Ne is 164.0625 NY.
50 Ne × 3.28125 = 164.0625 NY
