Don’t be confused by the use of the term ‘mile’ in nautical mile. It’s got nothing to do with the imperial statute mile. A nautical mile is derived from the distance at the Earth’s surface of the chord between two radials separated by an angle of one minute at the Earth’s centre. Degrees, minutes and seconds while not SI units are recognised measures under that system. A nautical mile is internationally acknowledged as being exactly 1852 metres having been standardised to the SI unit for length. Therefore a knot is 1.852 km/hour. And back to topic, can I point out that the term “shiny boat” is as much metaphorical as it is literal. Not all boats that shine are ‘shiny boats’. JP Never mind these new fangled metre things... a Nautical mile is, and will always be 6080 feet, otherwise I'll get lost! Howard 3 Link to comment Share on other sites More sharing options...
