How to Convert Linen Lea to Denier
- den = 14881.63944 ÷ NeL
- NeL = 14881.63944 ÷ den
- Example: convert 15 NeL to den: 14881.63944 ÷ 15 = 992.1092957 den
Formula
den = 14881.6394357 ÷ NeL
Derivation from SI units:
- Linen lea = number of 300-yard leas per pound, so tex = 1653.5 ÷ count
- 1 den = 1 g per 9000 m = 1/9 tex ≈ 1.111 × 10⁻⁷ kg/m (exact)
- Solving for den: den = 14881.6394357 ÷ NeL (a higher NeL means a lower den)
Both units are defined exactly, so the factor is exact. Linen Lea definition: linen lea; Denier definition: denier.
Worked examples
- A reading of 20 NeL converts to 744.0819718 den.
14881.63944 ÷ 20 = 744.0819718 den - A value of 40 NeL is 372.0409859 den.
14881.63944 ÷ 40 = 372.0409859 den

Where it's used
Linen Lea are used for linen and flax yarns, while denier appear in hosiery and tights (for example 15–40 den). 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 linen lea to denier?
den = 14881.63944 ÷ NeL. The two systems are inversely related, so divide the constant by the value; do not multiply. For example, 14881.63944 ÷ 15 = 992.1092957 den.
Why does a higher NeL give a lower den?
Linen Lea counts length per unit mass (an indirect system), while denier counts mass per unit length (a direct system). A finer yarn has a higher indirect number and a lower direct number.
Is the NeL to den 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).
