what is the diff w/ knots and miles?

Question

can any one tell me?

Answer 1

A knot is a unit of speed. The abbreviation preferred by maritime authorities in the USA[1], and Canada [2], as well as the Institute of Electrical and Electronics Engineers and the International Bureau of Weights and Measures is kn.

A common error that should be avoided is to use the term 'knot' to refer to the nautical mile itself.

The speed of a vessel relative to the fluid in which it travels is usually measured in knots. This may be referred to as 'boat speed', 'vessel speed' and, for aircraft, 'air speed'. For consistency in navigation, the speeds of relevant fluids, such as tidal streams, river currents and wind speeds, are also usually specified in knots. Knots are then also used to describe the actual speed of a vessel over the ground (SOG) and for its rate of progress toward a distant point

1 (international) knot is exactly equal to 1.852 kilometres per hour (km·h−1), and is approximately equal to the following:

101.268591 feet per minute
1.687810 feet per second
1.150779 mile (statute) per hour (mph)
0.99936 Admiralty knot
0.5144444 recurring metres per second

Answer 2

First off, your question is slightly in error....i think what you meant is miles per hour, since that is the proper term to use for rate of speed, which is what a knot is. A knot is the term used for the speed of a boat or ship, going back to the days when modern equipment was not available to measure the rate at which a vessel travels. Rope lines with knots tied at certain intervals were put in the water next to a ship, and the number of knots that a designated point on a ship passed during a certain period of time determined the speed of the ship in "knots". The term is still in use today. At sea, a nautical mile is 2000 yards, as opposed to a statute, or land mile, which is 1760 yards. This nautical distance allows for easier calculations of time, speed and distance. Mathematically, a knot is equal to approximately 1.1 miles per hour.

Answer 3

A "Knot" is a measurement of speed that equals Nautical Miles per hour as opposed to Statutory Miles per hour. The difference is between Statutory and Nautical miles. A statutory mile (or mile on land) is 5,280 feet . A Nautical mile is longer 6080 feet or 1.15 statutory miles. A Nautical Mile is equal to one minute of arc on the earth's surface. Since Nautical charts are measured in Degrees, Minutes and Seconds it is much easier to calculate distance in Nautical miles and speed in Knots.
