How to Convert Kilotex to Denier
- 1 ktex = 9000 den
- 1 den = 0.0001111111111 ktex
- Example: convert 15 ktex to den: 15 ktex = 15 × 9000 den = 135000 den
Formula
den = ktex × 9000
Derivation from SI units:
- 1 ktex = 1 g per metre = 1000 tex = 10⁻³ kg/m (exact)
- 1 den = 1 g per 9000 m = 1/9 tex ≈ 1.111 × 10⁻⁷ kg/m (exact)
- 1 ktex = 0.001 kg/m ÷ 1.111111111111 × 10⁻⁷ kg/m per den = 9000 den
Both units are defined exactly, so the factor is exact. Kilotex definition: kilotex; Denier definition: denier.
Worked examples
- A reading of 2.5 ktex converts to 22500 den.
2.5 ktex × 9000 = 22500 den - A value of 4 ktex is 36000 den.
4 ktex × 9000 = 36000 den

Where it's used
Kilotex are used for card and draw-frame sliver (about 3–5 ktex), while denier appear in hosiery and tights (for example 15–40 den). Both measure yarn count (linear density of yarns and fibres), so the conversion is a fixed factor.
