How to Convert Tex to Linen Lea
- NeL = 1653.515493 ÷ tex
- tex = 1653.515493 ÷ NeL
- Example: convert 15 tex to NeL: 1653.515493 ÷ 15 = 110.2343662 NeL
Formula
NeL = 1653.515492855 ÷ tex
Derivation from SI units:
- 1 tex = 1 g per 1000 m = 10⁻⁶ kg/m (exact)
- Linen lea = number of 300-yard leas per pound, so tex = 1653.5 ÷ count
- Solving for NeL: NeL = 1653.515492855 ÷ tex (a higher tex means a lower NeL)
Both units are defined exactly, so the factor is exact. Tex definition: tex; Linen Lea definition: linen lea.
Worked examples
- A reading of 16.4 tex converts to 100.8241154 NeL.
1653.515493 ÷ 16.4 = 100.8241154 NeL - A value of 37 tex is 44.68960792 NeL.
1653.515493 ÷ 37 = 44.68960792 NeL

Where it's used
Tex are used for yarn specifications in metric countries, 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 tex to linen lea?
NeL = 1653.515493 ÷ tex. The two systems are inversely related, so divide the constant by the value; do not multiply. For example, 1653.515493 ÷ 15 = 110.2343662 NeL.
Why does a higher tex give a lower NeL?
Linen Lea counts length per unit mass (an indirect system), while tex counts mass per unit length (a direct system). A finer yarn has a higher indirect number and a lower direct number.
Is the tex 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).
