How to Convert Tex to Kilotex
- 1 tex = 0.001 ktex
- 1 ktex = 1000 tex
- Example: convert 15 tex to ktex: 15 tex = 15 × 0.001 ktex = 0.015 ktex
Formula
ktex = tex ÷ 1000
Derivation from SI units:
- 1 tex = 1 g per 1000 m = 10⁻⁶ kg/m (exact)
- 1 ktex = 1 g per metre = 1000 tex = 10⁻³ kg/m (exact)
- 1 tex = 0.000001 kg/m ÷ 0.001 kg/m per ktex = 0.001 ktex
Both units are defined exactly, so the factor is exact. Tex definition: tex; Kilotex definition: kilotex.
Worked examples
- A reading of 16.4 tex converts to 0.0164 ktex.
16.4 tex × 0.001 = 0.0164 ktex - A value of 37 tex is 0.037 ktex.
37 tex × 0.001 = 0.037 ktex

Where it's used
Tex are used for yarn specifications in metric countries, while kilotex appear in card and draw-frame sliver (about 3–5 ktex). Both measure yarn count (linear density of yarns and fibres), so the conversion is a fixed factor.
