Tex to Ne: when you need it
A test report or a buyer's specification may give yarn in tex, while your spinner or yarn dealer quotes 30s or 40s. Dividing 590.54 by the tex gives the English count to order.
Real yarns rarely land on a round count. 20 tex works out to 29.53 Ne, just under a 30s, so the nearest standard count is usually the one to ask for, and the yarn lot's test report tells you the actual count.
Formula: Ne = 590.54 ÷ tex
Ne = 590.54 ÷ tex, from the exact pound (453.59237 g) and the 840-yard hank (768.096 m).
Worked example
20 tex: 590.54 ÷ 20 = 29.53 Ne.

FAQ
Questions
How do I convert tex to Ne?
Divide 590.54 by the tex: Ne = 590.54 ÷ tex. 20 tex: 590.54 ÷ 20 = 29.53 Ne.
What count is 30 tex?
19.68 Ne, which the market would treat as a 20s yarn. ASTM D2260 uses the same example: 30 tex is 19.7 cotton count.
What is 10 tex in Ne?
59.05 Ne, close to a 60s yarn. In denier it is 90.
What Ne is 100 tex?
5.905 Ne, a coarse yarn. In denier that is 900.
Why does my report show a slightly different count?
Some tables round 590.54 to 590.5 or 591. For 25 tex that moves the answer from 23.62 to 23.64 Ne. Measured counts also vary within a lot, so a few hundredths do not matter.
