Table of Conversion Factor for Textile Calculation

Conversion Factor for Textile Calculation:
In the path of textile calculation, we need to work with numerous number/count units of measurement. Because many of the mathematical theories we see require frequent conversion of units. Is for example,

Problem: 01
A wrapper’s beam containing 420 ends and a length of 2000 yards weights (net) 20 pounds. Find the beam count?

Solution:

Total continuous length of 420 ends = (2000 x 420 ) yards

So one lea (120 yards) weight = { (20 x 7000 x 120) ÷ (2000 x 420)grains }
= 20 grains

Hence beam count = 1000/20
= 50s (ANS.)

Math like above, we see there is given a length of 2000 yards weights(net) 20 pounds, but to find one lea weight, we must need to convert this 20 pounds into grains, for doing this we have multiplied 20 by 7000.

Problem: 02
A 30-yard length lap weight (after deducing the lap rod weight) 26.25 lbs. Find out the hank lap?

Solution:

One yard of lap weights = 26.25 / 30 lbs
=14 ozs.

Converting ozs.to grains = (14/16) x7000

Hank Lap = 8.33 ÷ { (14/16) x7000 }
= 0.00136 (ANS.)

Math like this, we are seeing when we get the weight of one yard of lap 26.25 / 30 lbs, for putting this weight into the second calculation of finding hank lap it needs to multiply by 16, as it requires the same value but in the unit named ounces that’s why before putting we have to convert multiplying it by 16.

The aim of this discussion is only to understand the necessity of knowing easy factors for converting values. That’s why it is very helpful to keep all the conversion factors on one page. Keeping it in mind we try to prepare a Table consists of all the conversion factors. Hope you would be benefited a lot.
