Formulae: Tex = 590.5 ÷ Ne · Nm = 1000 ÷ Tex · Denier = Tex × 9.
How the systems relate
Indirect systems (Ne, Nm) rise with fineness — a higher number is a finer yarn. Direct systems (Tex, Denier) rise with coarseness. Everything routes through Tex, so once you know the Tex you can reach any other system. Read the full explainer in our count guide.
