How to Convert Metric Count to Yorkshire Woollen Count
- 1 Nm = 1.937713468 NY
- 1 NY = 0.5160721729 Nm
- Example: convert 15 Nm to NY: 15 Nm = 15 × 1.937713468 NY = 29.06570202 NY
Formula
NY = Nm × 1.93771346819
Derivation from SI units:
- Nm = kilometres of yarn per kilogram, so tex = 1000 ÷ Nm
- Yorkshire woollen count = number of 256-yard skeins per pound, so tex = 1937.7 ÷ count
- 1 Nm = 0.001 kg/m ÷ 0.00193771346819 kg/m per NY = 1.93771346819 NY
Both units are defined exactly, so the factor is exact. Metric Count definition: metric count; Yorkshire Woollen Count definition: Yorkshire woollen count.
Worked examples
- A reading of 34 Nm converts to 65.88225792 NY.
34 Nm × 1.937713468 = 65.88225792 NY - A value of 68 Nm is 131.7645158 NY.
68 Nm × 1.937713468 = 131.7645158 NY
