Yarn Count Converter

Convert between direct and indirect yarn numbering systems.

Conversion Relationships

Tex = 590.54 / Ne
Nm = Ne × 1.6934
Denier = Tex × 9 = 5314.9 / Ne
Ne = 5314.9 / Denier

Direct Systems (Tex, Denier): Higher number = Thicker yarn.
Indirect Systems (Ne, Nm): Higher number = Finer yarn.

Standard Reference Benchmark

A standard 30s Ne ring-spun combed cotton yarn corresponds to:

  • 19.68 Tex
  • 177.16 Denier
  • 50.80 Nm
