Introduction:
In the path of textile calculation, we need to work with numerous number/count units of measurement. Because many of mathematical theories we see which requires 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 weights (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 unit named ounces .thats why before putting we have convert multiplying it by 16.

Aim of this discussion is only to understand you the necessity of knowing easy factors for converting values. Thats why it is very helpful to keep all the conversion factors in 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.
