Mr. Ashenhurst estimates the diameter of a 32’s cotton yarn at the 1148th part of an inch; but this is probably somewhat under the mark, and in the following table I have taken 1156th inch as the diameter of 32’s.
The variation in the thickness of any yarn, and the fact that they are not strictly cylindrical, renders measurements of little avail, but taken in conjunction with an examination of a range of woven cloths, the approximate or practical diameter can be estimated.
