What is "nautical mile" ?

Answer 1

A few times greater than usual mile used in sea travel. In Latin
"Nauticose" means sea voyager.
1 nautical mile = 6080 feet
It is now used in air travel also

Answer 2

"The nautical mile was historically defined as 1 minute of arc along a meridian (or in some instances any great circle) of the Earth."

But then, differences arise because the argument becomes which circle around the earth. Hence, we have sky nauticals and sea nauticals and standardized engineering nautical miles (6,000 ft. = 1 eng. nm). Nautical miles are useful in navigation within the formulas used to plot distance, position, speed so as to lend more meaningful numbers and easier multiple calculations

Answer 3

nautical mile, sea mile or nautimile is a unit of length. It is accepted for use with the International System of Units (SI), but it is not an SI unit.[1] The nautical mile is used around the world for maritime and aviation purposes. It is commonly used in international law and treaties, especially regarding the limits of territorial waters. It developed from the geographical mile.

Answer 4

Nautical mile is used in maritime and aeronautical studies. A nautical mile is slightly greater than a statutory mile, and takes into account the contours of the earth.

Answer 5

A nautical mile, sea mile or nautimile is a unit of length. It is accepted for use with the International System of Units (SI), but it is not an SI unit. The nautical mile is used around the world for maritime and aviation purposes. It is commonly used in international law and treaties, especially regarding the limits of territorial waters. It developed from the geographical mile.

The international standard definition is: 1 nautical mile = 1852 meters exactly.

There is no official international standard symbol for the unit nautical mile. The symbols M, NM, nm and nmi are commonly used in some areas (not to be confused with nm,the official symbol for nanometre , Nm, the official symbol for Newton metre )

The International Bureau of Weights and Measures (BIPM) in its International System of Units brochure lists the nautical mile in the table of units "currently accepted" for use with SI using M as a symbol, mentioning in a footnote other symbols, and stating that as yet there is no internationally agreed symbol.

Although nm is the official symbol for nanometre, there is little confusion because it is used in very different contexts, and differs by twelve orders of magnitude (one nautical mile = 1.852 trillion nanometres). Listings of aircraft flight ranges typically include both the "nm" (nautical mile) and "km" (kilometre) equivalents next to each other.

There are several national unit symbols in use (for example, mpk (meripeninkulma, "sea league") in Finnish, sm (Seemeile, "sea mile") in German, and M (sjómíla, "sea mile") in Icelandic). The People's Republic of China uses n mile as the national standard symbol with no s added for plural.

One nautical mile converts to:

0.998383 geographical mile
1.852 km (exact)
1.150779 mile (statute)
2025.372 yard
6076.1155 feet
1 meridian arc minute at sea-level surface distance

Answer 6

A mile is a unit of length, usually used to measure distance, in a number of different systems, including Imperial units, United States customary units and Norwegian/Swedish mil. Its size can vary from system to system, but in each is between 1 and 10 kilometers. In contemporary English contexts mile refers to either:

the statute mile of 5,280 feet (about 1,609 m), or 63360 inches
the international nautical mile of exactly 1,852 m (about 6,076 feet).
There have been several abbreviations for mile, with and without trailing period: mi, ml, m, M. NIST now uses and recommends "mi", but miles per hour are usually shortened to "mph", "m.p.h." or "MPH" instead of "mi/h".

Answer 7

A unit of length used in sea and air navigation, based on the length of one minute of arc of a great circle, especially an international and U.S. unit .

Based on the curvature and circumference of the Earth.

It is equal to 1,852 meters (about 6,076 feet). Also called sea mile.

To convert from miles (nautical) to:

feet, multiply by 6076.115.
kilometers, multiply by 1.852.
meters, multiply by 1852.
miles (statute), multiply by 1.1516.
yards, multiply by 2025.37.

Hope this helps!

Answer 8

A unit of length used in sea and air navigation, based on the length of one minute of arc of a great circle, especially an international and U.S. unit equal to 1,852 meters (about 6,076 feet). Also called sea mile.

Answer 9

(m)

A unit of length used in sea and air navigation, based on the length of one minute of arc of a great circle, especially an international and U.S. unit equal to 1,852 meters (about 6,076 feet). Also called sea mile.

Answer 10

This is unit of distance measure in SEA.
