Method and formula

Breaking Load (cN)=Tenacity (cN/tex)×Yarn TexTensile Strength (N/5cm)=(Threads per Inch2.54)×5×(Breaking Load100)×Correction×Float Factor\begin{aligned} \text{Breaking Load (cN)} &= \text{Tenacity (cN/tex)} \times \text{Yarn Tex} \\[0.5em] \text{Tensile Strength (N/5cm)} &= \left(\frac{\text{Threads per Inch}}{2.54}\right) \times \text{5} \times \left(\frac{\text{Breaking Load}}{100}\right) \times \text{Correction} \times \text{Float Factor} \end{aligned}
