THE PRIMARY STANDARD TO DETERMINE YARN THICKNESS IS WORSTED AT 500 YARDS/PER POUND.
Example: 3/9 count yarn
The first number of the fraction (3) is the number of plies. A ply is a
single strand, so this is 3-ply yarn.
The second number of the fraction (9) is the yarn thickness. This yarn
thickness means the yarn has been spun 9 times the standard length of 500: 9
x 500 = 4,500.
So, for this 3-ply yarn, the thickness number (4,500) is divided by the
number of strands (3) = 1,500 yards/per pound.
Good for standard machines or doubled for the bulky at 750 yards/per pound.
Example: 2/30 count yarn
2-ply yarn and (30 x 500) = 15,000 &#divide; 2 = 7,500 yards/per pound. Good for double-bed jacquard work.
Example: 4/18 count yarn
4-ply yarn and (18 x 500) = 9,000 &#divide; 4 = 2,250 yards/per pound. Good for single bed work or doubled for bulky.
Situation:
Let's say you take a trip to England this summer and see some British hand-knitting yarn in 100-gram skeins that say 302 meters each and you want to buy it, but there's no one around who can convert this to yarns or pounds so you can know how much to buy. There are two ways to handle this, really three.
(1) First, you can just know how to convert from meters to yarns and pounds because you're smarter than most of us.
(2) You can always be a good Girl or Boy Scout and carry the following handy little chart with you. You can use this same chart if you know that yarn count or an approximation of meters per 100 grams.

CONVERTING NUMBERS ON LABELS
302 Meters/100 Grams to Yards/Pound:
1,500 Yards/Pound to Meters:
1,500 yards x .9144 = 1,371 meters
1,371 meters to a pound &#divide; 4.54 = 302 meters per 100 grams
The better yarn comes from the first-spun yarn, like the best olive oil comes from the first pressing. You get longer and longer strands, less apt to break, therefore less likely to separate and pill. The more expensive yarn, because it is the best yarn, is what comes from the earlier spinning.
2/3 Cotton | 3 x 840 &#divide; 2 = 1,260 yards/per pound. | Standard (Double for Bulky) |
4/2 Cotton | 4 x 840 &#divide; 2 = 1,680 yards/per pound. | Standard (Double for Bulky) |
5/2 Cotton | 5 x 840 &#divide; 2 = 2,100 yards/per pound. | Standard (Double for Bulky) |
6/2 Cotton | 6 x 840 &#divide; 2 = 2,520 yards/per pound. | Standard (Single Bed) |
8/2 Cotton | 8 x 840 &#divide; 2 = 3,360 yards/per pound. | Double Bed (Double for Single Bed) |
10/2 Cotton | 10 x 840 &#divide; 2 = 4,200 yards/per pound. | Double Bed (Double for Single Bed) |
20/2 Cotton | 20 x 840 &#divide; 2 = 8,400 yards/per pound. | Double Bed (Double for Single Bed) |
Raw Cotton Cotton growing in a field and unusable for knitting. If you've seen cotton balls, you've seen pretty much what raw cotton on the plant resembles.
Carded or Combed Cotton Cotton that has been 'combed', the first stage of processing, to remove plant residue before spinning to a specific thickness. Usually quite soft, not at all recommended for fitted skirts due to 'seating out' problems, with a tendency to separate into plies, can break easily and will pill often.
Mercerized Cotton Carded cotton that has been spun to a specific thickness and then treated in an acid-solution bath to both set the yarn fibers and the colors. This yarn is usually quite strong, holds its color quite well and is much less likely to pill. Can sometimes be plied, twisted or basket-woven.
Gassed Cotton Mercerized cotton that has had all or most of the excess lint and/or fuzz burned off to bring the color to the surface. Gassed cotton often gives the illusion of iridescence.
