How to Convert Denier to Tex
- 1 den = 0.1111111111 tex
- 1 tex = 9 den
- Example: convert 150 den to tex: 150 den = 150 × 0.1111111111 tex = 16.66666667 tex
Formula
tex = den × 0.1111111111111
or tex = den ÷ 9
Derivation from SI units:
- 1 den = 1 g per 9000 m = 1/9 tex ≈ 1.111 × 10⁻⁷ kg/m (exact)
- 1 tex = 1 g per 1000 m = 10⁻⁶ kg/m (exact)
- 1 den = 1.111111111111 × 10⁻⁷ kg/m ÷ 0.000001 kg/m per tex = 0.1111111111111 tex
Both units are defined exactly, so the factor is exact. Denier definition: denier; Tex definition: tex.
Worked examples
- A 70 den nylon hosiery yarn is 7.777777778 tex.
70 den × 0.1111111111 = 7.777777778 tex - A 150 den polyester filament yarn is 16.66666667 tex.
150 den × 0.1111111111 = 16.66666667 tex

Frequently asked questions
How do I convert denier to tex?
Divide by 9, because denier is grams per 9000 m and tex is grams per 1000 m: 150 den = 16.66666667 tex.
Is denier a direct or an indirect count?
Direct, like tex: a higher number means a heavier, coarser yarn.
How many tex are in 1 denier?
1 den = 0.1111111111 tex.
Is the den to tex conversion exact?
Yes. Both units are defined exactly, so the ratio is exact; its decimal form does not terminate and is shown here to 10 significant figures (more with the precision selector).
