How to Convert Kilogram per Metre to Yorkshire Woollen Count
- NY = 0.001937713468 ÷ kg/m
- kg/m = 0.001937713468 ÷ NY
- Example: convert 15 kg/m to NY: 0.001937713468 ÷ 15 = 0.0001291808979 NY
Formula
NY = 0.00193771346819 ÷ kg/m
Derivation from SI units:
- The coherent SI unit of linear density: mass in kilograms per metre of length.
- Yorkshire woollen count = number of 256-yard skeins per pound, so tex = 1937.7 ÷ count
- Solving for NY: NY = 0.00193771346819 ÷ kg/m (a higher kg/m means a lower NY)
Both units are defined exactly, so the factor is exact. Kilogram per Metre definition: kilogram per metre; Yorkshire Woollen Count definition: Yorkshire woollen count.
Worked examples
- A reading of 0.00001 kg/m converts to 193.7713468 NY.
0.001937713468 ÷ 0.00001 = 193.7713468 NY - A value of 0.0001 kg/m is 19.37713468 NY.
0.001937713468 ÷ 0.0001 = 19.37713468 NY

Where it's used
Kilograms per Metre are used for ropes, cables and heavy tows, while Yorkshire woollen count appear in woollen-spun yarns for tweeds and blankets. Both measure yarn count (linear density of yarns and fibres), but one system is the inverse of the other, so a fixed constant is divided by the value.

Frequently asked questions
What is the formula for kilograms per metre to Yorkshire woollen count?
NY = 0.001937713468 ÷ kg/m. The two systems are inversely related, so divide the constant by the value; do not multiply. For example, 0.001937713468 ÷ 15 = 0.0001291808979 NY.
Why does a higher kg/m give a lower NY?
Yorkshire Woollen Count counts length per unit mass (an indirect system), while kilograms per metre counts mass per unit length (a direct system). A finer yarn has a higher indirect number and a lower direct number.
Is the kg/m to NY 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).
