Yarn Count:
Count is the numerical expression which expresses coarseness or fineness of yarn. It means that, the yarn count refers how much a yarn is fine or course.

Referring to different fiber yarns count :
 
  • Cotton and spun silk is the number of 840 yds. Lengths per lb.
  • Woollen (Yorkshire) is the number of 1600 yds. Lengths per lb.
  • Woollen Run is the number of 1600 yds. Lengths per lb.
  • Woollen cut is the number of 300 yds. Lengths per lb.
  • Worsted is the number of 560 yds. per lb.
  • Linen is the number of hanks of 300 yds. per lb.
  • Silk and man-made is the weight in grams of 9000 meters
  • One Denier = 0.0532 gm.
  • Cotton count × denier count = 5315
To convert worsted to woolen multiply by 2.1875 and for woolen to worsted multiply by 0.4571

Other systems for yarn count:
For general information various other systems pertaining to other fibers are briefly explained below. For example in woolen yarns there are:

(A) Yorkshire System: Which has a length unit of 1536 yards and the corresponding weight unit is 6 lbs. That is , the number of 1536 yard length pieces(this is termed as a skein) which weight 6 lbs. is the count. For calculation purpose this is reduced as 1536/6 = 256 yards per lb.

(B) American Run System:
Here the count (0f the woolen yarn) is the number of lengths (known as runs) of 100 yards that weight 1 ounce.

(C) American Cut System: This is also in the woolen yarn trade which means that count(American Cut) is the number of lengths of 300 yards (known as cut) that weight 1 pound.

Such count measures are also laid for yarns made from asbestos fiber, glass ,etc.

For asbestos: In British System the count is the number of hanks of 50 yds. Which weight 1 lb. In the American System the asbestos count is the number of length of 100 yards which weight 1 lb. The fiber glass count measure is the same as asbestos in American System.

For jute, hemp and flax: Count is the number lengths of 14400 yards(known as “spyndle”)that weight 1 lb.
