How to Convert Linen Lea to Decitex
- dtex = 16535.15493 ÷ NeL
- NeL = 16535.15493 ÷ dtex
- Example: convert 15 NeL to dtex: 16535.15493 ÷ 15 = 1102.343662 dtex
Formula
dtex = 16535.15492855 ÷ NeL
Derivation from SI units:
- Linen lea = number of 300-yard leas per pound, so tex = 1653.5 ÷ count
- 1 dtex = 1 g per 10 000 m = 0.1 tex = 10⁻⁷ kg/m (exact)
- Solving for dtex: dtex = 16535.15492855 ÷ NeL (a higher NeL means a lower dtex)
Both units are defined exactly, so the factor is exact. Linen Lea definition: linen lea; Decitex definition: decitex.
Worked examples
- A reading of 20 NeL converts to 826.7577464 dtex.
16535.15493 ÷ 20 = 826.7577464 dtex - A value of 40 NeL is 413.3788732 dtex.
16535.15493 ÷ 40 = 413.3788732 dtex

Where it's used
Linen Lea are used for linen and flax yarns, while decitex appear in polyester and nylon filament yarns (for example 167 dtex). 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 decitex?
dtex = 16535.15493 ÷ NeL. The two systems are inversely related, so divide the constant by the value; do not multiply. For example, 16535.15493 ÷ 15 = 1102.343662 dtex.
Why does a higher NeL give a lower dtex?
Linen Lea counts length per unit mass (an indirect system), while decitex 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 dtex 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).
