How to Convert Kilotex to Linen Lea
- NeL = 1.653515493 ÷ ktex
- ktex = 1.653515493 ÷ NeL
- Example: convert 15 ktex to NeL: 1.653515493 ÷ 15 = 0.1102343662 NeL
Formula
NeL = 1.653515492855 ÷ ktex
Derivation from SI units:
- 1 ktex = 1 g per metre = 1000 tex = 10⁻³ kg/m (exact)
- Linen lea = number of 300-yard leas per pound, so tex = 1653.5 ÷ count
- Solving for NeL: NeL = 1.653515492855 ÷ ktex (a higher ktex means a lower NeL)
Both units are defined exactly, so the factor is exact. Kilotex definition: kilotex; Linen Lea definition: linen lea.
Worked examples
- A reading of 2.5 ktex converts to 0.6614061971 NeL.
1.653515493 ÷ 2.5 = 0.6614061971 NeL - A value of 4 ktex is 0.4133788732 NeL.
1.653515493 ÷ 4 = 0.4133788732 NeL

Where it's used
Kilotex are used for card and draw-frame sliver (about 3–5 ktex), while linen lea appear in linen and flax yarns. Both measure yarn count (linear density of yarns and fibres), but one system is the inverse of the other, so a fixed constant is divided by the value.

Frequently asked questions
What is the formula for kilotex to linen lea?
NeL = 1.653515493 ÷ ktex. The two systems are inversely related, so divide the constant by the value; do not multiply. For example, 1.653515493 ÷ 15 = 0.1102343662 NeL.
Why does a higher ktex give a lower NeL?
Linen Lea counts length per unit mass (an indirect system), while kilotex counts mass per unit length (a direct system). A finer yarn has a higher indirect number and a lower direct number.
Is the ktex to NeL 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).
