If using the imperial units yards for distance and inches for target size, one has to multiply by a factor of 1000 ⁄ 36 ≈ 27.78, since there are 36 inches in one yard. distance in yards = target in inches angle in mrad × 27.78 {\displaystyle {\text{distance in yards}}={\frac {\text{target in inches}}{\text{angle in mrad}}}\times 27.78}
{{convert|123|cuyd|m3+board feet}} → 123 cubic yards (94 m 3; 40,000 board feet) The following converts a pressure to four output units. The precision is 1 (1 decimal place), and units are abbreviated and linked.
Conversions between units in the metric system are defined by their prefixes (for example, 1 kilogram = 1000 grams, 1 milligram = 0.001 grams) and are thus not listed in this article. Exceptions are made if the unit is commonly known by another name (for example, 1 micron = 10 −6 metre).
For measuring length, the U.S. customary system uses the inch, foot, yard, and mile, which are the only four customary length measurements in everyday use. From 1893, the foot was legally defined as exactly 1200 ⁄ 3937 m (approximately 0.304 8006 m). [13] Since July 1, 1959, the units of length have been defined on the basis of 1 yd = 0.9144 ...
For example, a wavenumber in inverse centimeters can be converted to a frequency expressed in the unit gigahertz by multiplying by 29.979 2458 cm/ns (the speed of light, in centimeters per nanosecond); [5] conversely, an electromagnetic wave at 29.9792458 GHz has a wavelength of 1 cm in free space.
Ends per inch (EPI or e.p.i.) is the number of warp threads per inch of woven fabric. [12] [22] In general, the higher the ends per inch, the finer the fabric is. Ends per inch is very commonly used by weavers who must use the number of ends per inch in order to pick the right reed to weave with. The number of ends per inch varies on the ...
An association football pitch may vary within limits of 90–120 m (98–131 yd) in length and 45–90 m (49–98 yd) in width. The recommended field size is 105 m × 68 m (115 yd × 74 yd) for major competitions such as the FIFA World Cup, UEFA European Championship and UEFA Champions League.
The United States adopted the conversion factor 1 metre = 39.37 inches by an act in 1866. [30] In 1893, Mendenhall ordered the physical realization of the inch to be based on the international prototype metres numbers 21 and 27, which had been received from the CGPM, together with the previously adopted conversion factor.
