The following chart is very important for most of the textile students. It contains basic unit conversions that are most commons.
Length:
1 spyndle | = 14,400 yd | |
1 hank | = 840 yards | = 7 leas |
1 meter | = 1.09361 yd | |
1 Ligne | = 0.635 mm | |
1 yd | = 36 " | |
Weight:
1 lb | = 7,000 grain |
1 kg | = 2.2046 lb |
1 oz | = .02834 kg |
Area:
1 oz/ yd^2 | = 33.096 gm/ m^2 |
Formula
Apparel:
Metric Ticker No. = Resultant Count X 3
Calculations & Formula:
Basic Time = Observed Time X Rating
SMV = Basic Time + Basic Time X Allowances = 3.04+ 3.04 X 15% = 3.5 min
TOG | = CLO X 1.55 |
E |  |
Textile Testing:
Moisture Regain (R) | = (W / D) X 100 |
Moisture Content (C) | = (W / W+D) X 100 |
Moisture Regain (R) | = 100 C / (100 - C) |
Drape co-efficient (F) | = (Actual projected area of specimen - Disk Area) / (Specimen area - Disk area) |
Wear Index | = (Wt. loss in mg X No. of Cycle Tested) / 1000 |
Yarn:
