2 Metric count (Nm): This system measures the Calculation
number of 1000-meter lengths of yarn per kilogram.
NeL=20×2.8
3 Worsted count (NW): This system measures the NeL=56
number of 560-yard lengths of yarn per pound.
Result: A 20 Ne yarn is equivalent to 56 NeL.
4 Linen count (NeL): This system measures the
number of 300-yard lengths of yarn per pound. Example 4: Plied Yarn Conversion (Nm to Ne)
Conversion formula Scenario: You have a 2/48 Nm yarn (meaning two
To convert yarn count from one indirect system to another, strands of 48 Nm yarn plied together). You need to find
its equivalent single yarn count in Ne.
use the following formulas:
Step 1: Find the effective single yarn count in Nm.
1 Ne (English Cotton Count) to Nm (Metric Count)
For plied yarns, the effective count is the single yarn
- Nm=Ne×1.693
count divided by the number of plies.
- Ne=Nm×0.5905 (or Nm/1.693)
Effective Nm = 48 Nm / 2 = 24 Nm
2 Ne (English Cotton Count) to Nw (Worsted Count)
Step 2: Convert the effective single yarn count from Nm
- Nw=Ne×1.5 to Ne.
- Ne=Nw×0.6667 (or Nw/1.5) Formula: Ne=Nm×0.5905
3 Ne (English Cotton Count) to NeL (Linen Count) Calculation

- NeL=Ne×2.8 (since 840/300=2.8) Ne=24×0.5905
- Ne=NeL×0.357 (or NeL/2.8) Ne=14.172
Examples of indirect to indirect conversions Result: A 2/48 Nm yarn is equivalent to approximately
Example 1: Metric Count (Nm) to English Cotton Count 14.17 Ne. This means it has the fineness of a single

Calculation Formula: Nw=Nm×0.8858

Ne=40×0.5905 Calculation
Ne=23.62 Nw=80×0.8858
Result: A 40 Nm yarn is approximately 23.62 Ne. Nw=70.864
Example 2: Worsted Count (Nw) to English Cotton Result: An 80 Nm yarn is approximately 70.86 Nw.

Formula: Ne=Nw×0.6667 a higher count number indicates a coarser (thicker) yarn.
Calculation Common direct yarn count systems

Ne=60×0.6667 Here are the most common direct yarn count systems:
Ne=40.002 • Tex (T): The weight in grams of 1,000 meters (1
kilometer) of yarn. This is an international standard.
Result: A 60 Nw yarn is approximately 40 Ne.
• Decitex (dtex): The weight in grams of 10,000 meters
Example 3: English Cotton Count (Ne) to Linen Count of yarn. (1 Tex = 10 Decitex).

its equivalent count be in the Linen system (NeL)?
Formula: NeL=Ne×2.8
