Method and formula

S (stitch/sq. meter)=Course Per Inch×Wales Per Iinch0.02542GSM=Yarn Count (Tex)×S×Loop Length (meters)1000\begin{aligned} \text{S (stitch/sq. meter)} &= \frac{\text{Course Per Inch} \times \text{Wales Per Iinch}}{0.0254^2} \\[1em] \text{GSM} &= \frac{\text{Yarn Count (Tex)} \times S \times \text{Loop Length (meters)}}{1000} \end{aligned}
