The informal term "metric mile" is used in some countries, in sports such as track and field athletics and speed skating, to denote a distance of 1,500 metres (0.932 miles). The 1500 meters is the premier middle distance running event in Olympic sports. In United States high-school competition, the term is sometimes used for a race of 1,600 ...
The first metric Melbourne Cup was raced in November 1972. An early change was the metrication of horse racing. This was facilitated because the furlong (one-eighth of a mile) is close to 200 m. Therefore, the Melbourne Cup was changed from 2 mi to 3,200 m, a reduction of 19 m or about 0.6%. The first metric Melbourne Cup was raced in November ...
Metric signs and metric measurements were removed for the 2009 edition and replaced with an appendix of metric conversion tables. This is in marked contrast to the position in the (largely metric) United Kingdom , where metric road signs are prohibited by law (except for those denoting widths and height restrictions, which include both metric ...
From 1630 to 1718 a millia was 5,564 feet (1,696 metres), making a geographical league of four millias equal 22,256 feet (6,784 m or 3.663 modern nautical miles). But from 1718 through the 1830s the millia was defined as the equivalent of just over 5,210 feet, giving a shorter geographical league of just over 20,842 feet (6,353 m or 3.430 ...
A metric mile or an Olympic mile is a colloquial term used in some countries for the 1500 meters, the premier middle distance running event in international track and field. The term 'metric mile' (0.93 statute miles) was applied to this distance because it approximates one statute mile (1609.344 m). [ 1 ]
In contrast, in much of southern Ontario the basic survey grid was based on a mile-and-a-quarter (1.25 mi), which corresponds almost exactly to a 2-kilometre grid and which makes miles no more natural than kilometres. 1.25 mi is equal to 100 chains (or 10 furlongs) and it was that sized grid that was used in the original surveys and thus would ...
In radar-related subjects and in JTIDS, a data mile is a unit of distance equal to 6,000 feet (1,829 metres; 0.9875 nautical miles; 1.136 miles). An international mile is 0.88 data mile. The speed of light is 299,792,458 metres per second (983,571,056 ft/s), or about one foot per nanosecond .
The base unit in the International System of Units (SI) is the meter, defined as "the length of the path travelled by light in vacuum during a time interval of 1 ⁄ 299792458 seconds."
