Convert Kilotex to Decitex (ktex to dtex)
1 kilotex (ktex) = 10000 decitex (dtex). 1 dtex = 0.0001 ktex. Example: 15 ktex = 15 × 10000 = 150000 dtex.

How to Convert Kilotex to Decitex
- 1 ktex = 10000 dtex
- 1 dtex = 0.0001 ktex
- Example: convert 15 ktex to dtex: 15 ktex = 15 × 10000 dtex = 150000 dtex
Formula
dtex = ktex × 10000
Derivation from SI units:
- 1 ktex = 1 g per metre = 1000 tex = 10⁻³ kg/m (exact)
- 1 dtex = 1 g per 10 000 m = 0.1 tex = 10⁻⁷ kg/m (exact)
- 1 ktex = 0.001 kg/m ÷ 1 × 10⁻⁷ kg/m per dtex = 10000 dtex
Both units are defined exactly, so the factor is exact. Kilotex definition: kilotex; Decitex definition: decitex.
Worked examples
- A reading of 2.5 ktex converts to 25000 dtex.
2.5 ktex × 10000 = 25000 dtex - A value of 4 ktex is 40000 dtex.
4 ktex × 10000 = 40000 dtex

Where it's used
Kilotex are used for card and draw-frame sliver (about 3–5 ktex), while decitex appear in polyester and nylon filament yarns (for example 167 dtex). Both measure yarn count (linear density of yarns and fibres), so the conversion is a fixed factor.
