The mile, sometimes the international mile or statute mile to distinguish it from other miles, is a British imperial unit and United States customary unit of length; both are based on the older English unit of length equal to 5,280 English feet, or 1,760 yards. The statute mile was standardised between the Commonwealth of Nations and the United ...
10,000 metres is the slightly longer metric derivative of the 6-mile (9,656.1-metre) run, an event common in countries when they were using the imperial measurement system. 6 miles was used in the Commonwealth Games until 1966 and was a championship in the United States in non-Olympic years from 1953 to 1973.
nautical units. 0.539 96 nmi. The kilometre ( SI symbol: km; / ˈkɪləmiːtər / or / kɪˈlɒmətər / ), spelt kilometer in American English and Philippine English, is a unit of length in the International System of Units (SI), equal to one thousand metres ( kilo- being the SI prefix for 1000 ). It is the preferred measurement unit to ...
The square kilometre ( square kilometer in American spelling; symbol: km2) is a multiple of the square metre, the SI unit of area or surface area . 1 km 2 is equal to: 1,000,000 square metres (m 2) 100 hectares (ha) It is also approximately equal to: 0.3861 square miles [ 2] 247.1 acres [ 3] Conversely:
A nautical mile is a unit of length used in air, marine, and space navigation, and for the definition of territorial waters. [2] [3] [4] Historically, it was defined as the meridian arc length corresponding to one minute ( 1 / 60 of a degree) of latitude at the equator, so that Earth's polar circumference is very near to 21,600 nautical miles (that is 60 minutes × 360 degrees).
A light-year, alternatively spelled light year ( ly or lyr[ 3] ), is a unit of length used to express astronomical distances and is equal to exactly 9,460,730,472,580.8 km ( Scientific notation: 9.4607304725808 × 10 12 km), which is approximately 5.88 trillion mi.
A furlong is a measure of distance in imperial units and United States customary units equal to one-eighth of a mile, equivalent to any of 660 feet, 220 yards, 40 rods, 10 chains or approximately 201 metres. It is now mostly confined to use in horse racing, where in many countries it is the standard measurement of race lengths, and agriculture ...
3.2808. The metre per second is the unit of both speed (a scalar quantity) and velocity (a vector quantity, which has direction and magnitude) in the International System of Units (SI), equal to the speed of a body covering a distance of one metre in a time of one second. According to the definition of metre, [ 1] 1 m/s is exactly of the speed ...
