**Yarn Count System:**

The count is the numerical expression that expresses the coarseness or fineness of the yarn. It means that the **yarn count** refers to how much yarn is fine or course.

**Referring to different fiber yarn 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.
- Woolen 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) that weight 6 lbs. is the count. For calculation purposes, 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 length of 100 yards which weighs 1 lb. The fiberglass count measure is the same as asbestos in American System.

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