1.1These tables include (1) a series of conversion factors required to convert the number of a yarn measured in a specific system to the equivalent number measured in various other systems (see Table 1), and (2) specific equivalent numbers for yarns measured in various systems (see Table 2).

Examples of Table 1 use:
1)The English worsted count equivalent to a cotton count of 10 is 1.5 times 10, or 15 English worsted count.
2)The cotton count equivalent to 30 tex is 590.54 divided by 30, or 19.7 cotton count.
1.2The content is basically consistent with recommendations of the International Organization for Standardization (ISO) Standard 2947.
1.3The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
