the width of the roll, thus the same area as a piece of one quarter yard cut from the full width of the roll; these pieces are popular for patchwork and quilting. The term "fat eighth" is also used, for a piece of one quarter yard from half the roll width, the same area as one eighth cut from the roll. Equivalences For purposes of measuring cloth, the early yard was divided by the binary method into two, four, eight and sixteen parts. The two most common divisions were the fourth and sixteenth parts. The quarter of a yard (9 inches) was known as the "quarter" without further qualification, while the sixteenth of a yard (2.25 inches) was called a nail. The eighth of a yard (4.5 inches) was sometimes called a finger, but was more commonly referred to simply as an eighth of a yard, while the half-yard (18 inches) was called "half a yard". Other units related to the yard, but not specific to cloth measurement: two yards are a fathom, a quarter of a yard (when not referring to cloth) is a span. Conversions international yard (defined 1959): 1250 (international) yards = 1143 meters 1 (international) yard = 0.9144 meters (exact) 1 (international) statute mile = 8 international furlongs = 80 international chains = 1760 (international) yards pre-1959 US yard'' – defined 1869, implemented 1893, deprecated 2023 For survey purposes, certain pre-1959 units were retained, usually prefaced by the word "survey," among them the survey inch, survey foot, and survey mile, also known as the statute mile. The rod and furlong exist only in their pre-1959 form and are thus not prefaced by the word "survey." However, it is not clear if a "survey yard" actually exists. If it did, its hypothetical values would be as follows: 3937 survey yards = 3600 meters 1 survey yard ≈ meters 1 survey mile = 8 furlongs = 80 chains = 1760 survey yards Comparing international yards and survey yards (international) yards = survey yards = meters 1 (international) yard = survey yards (exact) 1 (international) mile = survey miles(exact) See also Guz, the yard of Asia 3 ft gauge railways Vara Yardstick Notes References Citations Bibliography . . . . . . . . . . . . . & & .
