Nautical mile

A nautical mile is a unit of measurement used in both air and marine navigation, for the definition of territorial waters. It was defined as one minute of latitude along any line of longitude. Today the international nautical mile is defined as 1852 metres; the derived unit of speed is one nautical mile per hour. There is no single internationally agreed symbol, with several symbols in use. M is used as the abbreviation for the nautical mile by the International Hydrographic Organization. NM is used by the International Civil Aviation Organization. Nmi is used by the Institute of Electrical and Electronics Engineers and the United States Government Publishing Office; the word mile is from the Latin word for a thousand paces: mille passus. Navigation at sea was done by eye until around 1500 when navigational instruments were developed and cartographers began using a coordinate system with parallels of latitude and meridians of longitude. By the late 16th century, Englishmen knew that the ratio of distances at sea to degrees were constant along any great circle such as the equator or any meridian, assuming that Earth was a sphere.

Robert Hues wrote in 1594 that the distance along a great circle was 60 miles per degree, that is, one nautical mile per arcminute. Edmund Gunter wrote in 1623. Thus, Hues explicitly used nautical miles. Since the Earth is not a perfect sphere but is an oblate spheroid with flattened poles, a minute of latitude is not constant, but about 1861 metres at the poles and 1843 metres at the Equator. France and other metric countries state that in principle a nautical mile is an arcminute of a meridian at a latitude of 45°, but, a modern justification for a more mundane calculation, developed a century earlier. By the mid 19th century France had defined a nautical mile via the original 1791 definition of the metre, one ten-millionth of a quarter meridian, thus 10,000,000 m/90 × 60 = 1851.85 m ≈ 1852 m became the metric length for a nautical mile. France made it legal for the French Navy in 1906, many metric countries voted to sanction it for international use at the 1929 International Hydrographic Conference.

Both the United States and the United Kingdom used an average arcminute a minute of arc of a great circle of a sphere having the same surface area as the Clarke 1866 ellipsoid. The authalic radius of the Clarke 1866 ellipsoid is 6,370,997.2 metres. The resulting arcminute is 1853.2480 metres. The United States chose five significant digits for its nautical mile, 6080.2 feet, whereas the United Kingdom chose four significant digits for its Admiralty mile, 6080 feet. In 1929, the international nautical mile was defined by the First International Extraordinary Hydrographic Conference in Monaco as 1,852 metres; the United States did not adopt the international nautical mile until 1954. Britain adopted it in 1970, but legal references to the obsolete unit are now converted to 1853 metres; the metre was defined as ​1⁄10,000,000 of the length of the meridian arc from the North pole to the equator, thus one kilometre of distance corresponds to one centigrad of latitude. The Earth's circumference is therefore 40,000 km.

The equatorial circumference is longer than the polar circumference – the measurement based on this is known as the geographical mile. Conversion of units Orders of magnitude

Burnside Street

Burnside Street is a major thoroughfare of Portland, in the U. S. state of Oregon, one of a few east–west streets that run uninterrupted on both sides of the Willamette River. It serves as the dividing line between South Portland, its namesake bridge, Burnside Bridge, is one of the most traversed in Portland. In Gresham between the east 18300 block to Mt. Hood Hwy, Burnside runs southeast-northwest and is no longer the divide between northeast and southeast on the City of Portland-Multnomah County street grid. Additionally, SE Burnside St becomes NW Burnside Road at SE 202nd/NW Birdsdale Ave, NE Burnside Rd at N Main Ave in Gresham. Burnside Road’s eastern terminus is where it meets Mt. Hood Hwy, E Powell Blvd, SE Powell Valley Road. What is now Burnside Street was named B Street east of Southwest 16th Avenue and Washington Street west of S. W. 16th. In 1891, B Street was renamed for Portland merchant David Burnside, in 1933 Washington Street west of SW 16th was renamed Burnside Street. Burnside became Portland's principal east–west axis following the 1912 Bennett Plan, soon becoming one of the widest streets in the city.

The street runs from SW Barnes Road in Sylvan-Highlands to the Mount Hood Highway in Gresham, a distance of over 17 miles. It crosses the Willamette River via the Burnside Bridge. For a number of years, the portion of Burnside between NW 19th Avenue and NE Sandy Boulevard was designated U. S. Route 30, it is served by TriMet bus line 20 between Barnes Road and NE/SE 102nd Avenue, several MAX Blue Line light-rail stations are located along its route in East Portland between 102nd Avenue and Ruby Junction.
