Volume was measured in ngogn (equal to 1000 cubic potrzebies), mass in blintz (equal to the mass of 1 ngogn of halva, which is "a form of pie [with] a specific gravity of 3.1416 and a specific heat of .31416"), and time in seven named units (decimal powers of the average earth rotation, equal to 1 "clarke").
In running events up to 200 m in distance and in horizontal jump events, wind assistance is permitted only up to 2.0 m/s. In decathlon or heptathlon, average wind assistance of less than 2.0 m/s is required across all applicable disciplines; and maximum of 4.0 m/s in any one event. As an exception, according to rule 36.2, specific event ...
However, in international competitions such as the Olympics the term "mile" almost always refers to a distance of 1,500 meters, which is 109.344 meters shorter than an Imperial mile, even though four "full" laps of a 400 meter track is equal to 1,600 meters. Accurate times for the mile run (1.609344 km) have been recorded since 1850, when the ...
The data mile is used in radar-related subjects and is equal to 6,000 feet (1.8288 kilometres). [90] The radar mile is a unit of time (in the same way that the light year is a unit of distance), equal to the time required for a radar pulse to travel a distance of two miles (one mile each way). Thus, the radar statute mile is 10.8 μs and the ...
Respectively, these square divisions of land are approximately 80 chains (one mile or 1.6 km), 40 chains (half a mile or 800 m), and 20 chains (a quarter mile or 400 m) on a side. The chain is still used in agriculture: measuring wheels with a circumference of 0.1 chain (diameter ≈ 2.1 ft or 64 cm) are still readily available in Canada and ...
3200 meters is an uncommon long middle-distance, or short long-distance, track and field running event that is 200 m longer than the much more common 3,000 metre run, and slightly shorter than the two mile run.
Although a statute mile today is equal to a length of 5,280 feet, the distance of the English mile gained its current definition of 1,760 yards through a statute of the Parliament of England in 1593. [6] Thus, the history of the mile run began in England and it initially found usage within the wagered running contests of the 18th and 19th century.
