It is a relatively uncommon non-championship event for indoor track and field. The history of the event lies in the 60-yard dash, which is about 5 inches shorter than 55 metres. Since the 1960s almost all countries have used metric measurements for track and field, hence the standard sprint distances for indoor competition have been 50 metres ...
Conversion of the Mach unit of speed depends on the altitude at which the speed is measured. That altitude should be specified either in feet (for example, |altitude_ft=10,000) or in metres (for example, |altitude_m=3,749). The altitude cannot be determined accurately and only a whole number is accepted. Examples:
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).
Because the distances are so similar, a conversion of 0.01 seconds is sometimes applied in statistical lists to convert 60 yd hurdle marks to equivalent 55 m hurdles times. [1] The 70 yards hurdles was also an uncommon distance held indoors beginning at the 1956 USA Indoor Track and Field Championships and ending by the 1963 Championships. [2]
15.24 meters – width of an NBA basketball court (50 feet) 18.44 meters – distance between the front of the pitcher's rubber and the rear point of home plate on a baseball field (60 feet, 6 inches) [125] 20 meters – length of cricket pitch (22 yards) [126] 27.43 meters – distance between bases on a baseball field (90 feet)
This is a list of the NCAA Division I indoor champions in the 60 meters, 55 meters, or 60 yards. Generally the imperial distance was contested until 1983, the 55 meter dash was held from 1984 to 1999, and the 60 meters was contested thereafter. Hand timing was used until 1975, while starting in 1976 fully automatic timing was used. [1]
By default, the output value is rounded to adjust its precision to match that of the input. An input such as 1234 is interpreted as 1234 ± 0.5, while 1200 is interpreted as 1200 ± 50, and the output value is displayed accordingly, taking into account the scale factor used in the conversion.
The basic unit of length in the imperial and U.S. customary systems is the yard, defined as exactly 0.9144 m by international treaty in 1959. [2] [10] Common imperial units and U.S. customary units of length include: [11] thou or mil (1 ⁄ 1000 of an inch) inch (25.4 mm) foot (12 inches, 0.3048 m) yard (3 feet, 0.9144 m)
