Useful Conversion Factors
|
| Quantity to be converted | To be converted into | Conversion Details |
|---|---|---|
| Cotton Count Ne | Tex | Tex= 590.5/Cotton Count |
| Metric Count Nm | Tex | Tex= 1000/Metric Count |
| cotton Count Ne | Denier | Denier = 5315/Cotton Count(Ne) |
| Cotton Count(Ne) | Worsted Count | Worsted Count = Cotton Count(Ne) * 1.5 |
| Denier | Tex | Tex = Denier/9 |
| Denier | Decitex | Decitex = Denier * 1.11 |
| Denier | Tex | Tex= Denier * 0.1111 |
| Denier | Microaire(mircogrms/inch) | Micronaire = Denier * 2.822 |
| Micronaire(micrograms/inch) | Denier | Denier = Micronaire*0.354 |
| Newton | Kgf | Kgf = 9.81 * Newton |
| gf/den | milliNewton/tex,mN/tex | mN/tex = 88.3 * gf/den |
| Kg | Candy | Candy = 355.6Kg |
| Kg | Metric Ton | Metric Ton = Kg * 1000 |
| Gr/yd | Kilotex | Kilotex = 0.07087 * Gr/yd |
| Grms/yd | Kilotex | Kilotex = 1.094 * Grms/yd |
| Twist Factor(conventional) = (TPI/(Count^0.5) | Twist Factor (SIunits)= Turns/cm * (Tex^0.5) | Turns/cm * (Tex^0.5) = 9.57 *TPI/(Count^0.5) |
| Pascal(Newton/sq meter) | Kgf/sq cm | Pascal = Kgf/sq cm * 9.806 * 10000 |
| Cover factor (conventional) = (Threads/inch)/(cotton count)^0.5 | Cover factor(SI) = (Threads/cm)×tex×10-1 | Cover factor(SI) = Cover factor(conventional)×0.957 |
Miscellaneous Information
1 hectare = 2.47 acre = 10000 sq metre1 metric Tonne = 1000 Kg = 2204.6 lb = 10 quintal
1 ton = 200cwt =2240 lb
1quintal q = 100kg
1lbs/sqin = 0.070307 kg/sq cm
If c1 = warp count
c2 = weft count
p1 = ends/inch
p2 = picks/in
r1 = crimp of warp
r2 = crimp of weft
then GSM grams/sq metre) of fabric = 23.25[p1(1+ r1)/c1 + p2(1 + r2)/c2]
Break Even Point = TFC/SUP - VCUP
TFC = Total fixed costs
SUP = Selling price/unit production
VCUP = Variable costs/unit of production
Debt Servicecoverage ratio (DSCR) = Net Revenue available for debt service/ Loan repayment (principal + interest)
