1.Formula: Count
*Count= L/LuX Wu/W(Indirect system)
*Count=Lu/LXW/Wu (Direct system)
2.Formula: Diameter of yarn
*Diameter of yarn= 1/28 root count
3.Formula: G.S.M
*G.S.M=(EPI/Count+PPI/Count)X 25.6
4.Formula: Cover factor
*Cover factor=(EPI/ root count+PPI/ root count)X 0.88 to 1(according to weave)
5.Formula: Grey EPI
Grey EPI=(F.EPI X F.Width)/G.Width
6.Formula: Grey Width
*Grey width=(F.EPI X F.Width)/G.EPI
