In the above formula, "36" is the conversion factor between yards and inches. Conversely, the group size of 1 arcminute at 100 yards (the most commonly used sighting-in distance in North America ) can also be calculated:
as a percentage, the formula for which is which is equivalent to the tangent of the angle of inclination times 100. In Europe and the U.S. percentage "grade" is the most commonly used figure for describing slopes.
In astronomy, it is typically difficult to directly measure the distance to an object, yet the object may have a known physical size (perhaps it is similar to a closer object with known distance) and a measurable angular diameter. In that case, the angular diameter formula can be inverted to yield the angular diameter distance to distant objects as
A Canadian football field is 65 yards (59 m) wide and 110 yards (100 m) long with end zones adding a combined 40 yards (37 m) to the length, making it 87,750 square feet (8,152 m 2) or 0.8215 ha (2.030 acres).
The Compositio redefined the yard, foot, inch, and barleycorn to 10 ⁄ 11 of their previous value. [dubious – discuss] However, it retained the Anglo-Saxon rod of 15 x 11 ⁄ 10 feet (5.03 metres) and the acre of 4 × 40 square rods. Thus, the rod went from 5 old yards to 5 + 1 ⁄ 2 new yards, or 15 old feet to 16 + 1 ⁄ 2 new feet. The ...
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. [62] The eighth of a yard (4.5 inches) was sometimes called a finger, [63] but was more commonly referred to simply as an eighth of a yard, while the half-yard (18 inches) was called "half a ...
Similarly, an inch-pound (or pound-inch) is the torque of one pound of force applied to one inch of distance from the pivot, and is equal to 1 ⁄ 12 lbf⋅ft (0.1129848 N⋅m). It is commonly used on torque wrenches and torque screwdrivers for setting specific fastener tension.
Australia uses metric paper sizes for office use and home printing (most commonly A4 size, being 210 × 297 mm) [49] However, the term dots per inch (dpi) is still used when referring to printing resolution. [50] The photo printing industry uses both imperial and metric sizes for photograph dimensions (e.g. 4 × 6 inches as well as 10 × 15 cm).
