Yarn Tenacity Conversion

Convert yarn tenacity and estimate yarn strength.

RKM

g/denier

cN/tex

g/tex

Strength (g)

Method and formula

\begin{aligned} \text{g/denier} &= \frac{\text{RKM}}{9.015} \\[1em] \text{g/tex} &= \text{RKM} \\[1em] \text{cN/tex} &= \frac{\text{RKM}}{1.02} \\[1em] \text{Strength (g)} &= \text{g/denier} \times \frac{5315}{\text{Yarn Count (Ne)}} \end{aligned}

Variable	Expected entry
Yarn tenacity	Enter a positive measured value.
Tenacity unit	Choose: RKM, g/denier, g/tex, cN/tex
Yarn count (Ne)	Enter a positive measured value.
