How to Convert Denier to Linen Lea
- NeL = 14881.63944 ÷ den
- den = 14881.63944 ÷ NeL
- Example: convert 15 den to NeL: 14881.63944 ÷ 15 = 992.1092957 NeL
Formula
NeL = 14881.6394357 ÷ den
Derivation from SI units:
- 1 den = 1 g per 9000 m = 1/9 tex ≈ 1.111 × 10⁻⁷ kg/m (exact)
- Linen lea = number of 300-yard leas per pound, so tex = 1653.5 ÷ count
- Solving for NeL: NeL = 14881.6394357 ÷ den (a higher den means a lower NeL)
Both units are defined exactly, so the factor is exact. Denier definition: denier; Linen Lea definition: linen lea.
Worked examples
- A reading of 40 den converts to 372.0409859 NeL.
14881.63944 ÷ 40 = 372.0409859 NeL - A value of 150 den is 99.21092957 NeL.
14881.63944 ÷ 150 = 99.21092957 NeL

Where it's used
Denier are used for hosiery and tights (for example 15–40 den), 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 denier to linen lea?
NeL = 14881.63944 ÷ den. The two systems are inversely related, so divide the constant by the value; do not multiply. For example, 14881.63944 ÷ 15 = 992.1092957 NeL.
Why does a higher den give a lower NeL?
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 den 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).
