Yarn Count Converter (Ne, Nm, Tex, Denier)
Convert yarn count between English Cotton Count (Ne), Metric Count (Nm), Tex, Denier, Worsted Count (NeW), and Linen Lea. Live bidirectional textile converter.
A precision textile engineering tool for spinners, knitters, weavers, and fabric researchers. Convert any yarn thickness across direct systems (Tex, Denier) and indirect count systems (Cotton Ne, Metric Nm, Worsted NeW, Linen Lea) with instant live formulas.
Key Features & Calculations
- Direct systems: Tex (g/1000m) & Denier (g/9000m)
- Indirect systems: Cotton Count (Ne), Metric (Nm), Worsted (NeW), Linen (Lea)
- Real-time multi-system synchronization
- Shows standard trade yarn examples (30s cotton, 150D polyester, 60s lawn)
- Explains direct vs indirect count mathematical inversion
Frequently Asked Questions
What is the difference between direct and indirect yarn counts?
In direct systems (Tex, Denier), the number measures weight per fixed length—higher numbers mean thicker yarns. In indirect systems (Cotton Ne, Metric Nm, Lea), the number measures length per fixed weight—higher numbers mean finer, thinner yarns.
What does "40s cotton" mean?
"40s cotton" refers to a 40 Ne (English Cotton Count) yarn. It means 40 hanks of 840 yards each weigh 1 pound. It is a fine, lightweight yarn used for quality shirting and premium bedsheets.
How do you convert Denier to Tex?
Tex equals Denier divided by 9 (Tex = Denier ÷ 9). For example, a 150 Denier polyester thread equals 16.7 Tex.
