On the number of textile yarns
(1 pound) The length of the yarn at a given moisture regain is a multiple of 840 yards. A few 840 yards are a few yarns in English.
Is often said that the British count, English: SIZE, all commonly used S to do short.
Simply said that the length of the unit weight, the longer the length will be fine, so the greater the number of yarn the more thin!
