To sailors a knot is a speed. What is it translated into miles per hour?

It is 1.15 MPH or 6076 feet per hour. Take your pick on what conversion you want. Good luck :)

One nautical mile is 1.1508 statute miles. 60 nautical miles is one degree latitude, or 1 nautical mile is 1 minute of latitude. A knot is 1 nautical mile per hour.

Well dear.........the science teacher is correct.........but if I'm not mistaken, there are variables to add to this. eg it depends where you are in the world. If you are at very high latitudes the degree of arc is less (distance) than if you are on the Equator. Yours Dorothy Mills (Mrs)

1 knot = 1 nautical mile/hour = 1.852 km/h exactly. This is based on the internationally agreed length of the nautical mile, as adopted by the US in 1954, the UK in 1970 and other countries. This is the definition used in most, if not all, modern circumstances. Knot is sometimes mistakenly used to refer to the nautical mile itself, but this is incorrect. The speed of a vessel relative to the fluid itself, and not land, is referred to as 'boat speed' or, for aircraft, 'air speed' and is usually measured in knots. If the medium is flowing, this differs from the ground velocity by the velocity of the medium. Velocity made good refers to ground velocity and may also be expressed in knots in navigation. Conversions 1 knot is roughly equivalent to: 101.268591 foot/minute 1.687810 foot/second 0.5144444 metres per second (m•s−1) 1.852 kilometres per hour (km•h−1) (exact) 1.150779 mile (statute)/hour (mph) [edit] In some sailing ships, speed was measured by casting the chip log from the stern. The log was relatively immobile, and attached by line to a reel. Some sources suggest that knots placed at a distance of 47 feet 3 inches (14.4018 m) passed through a sailor's fingers, while another used a 28 second sandglass to time the operation. The knot count would be reported and used in the sailing master's dead reckoning and navigation. This method gives a value for the knot of 20.25 in/s, or 1.85166 km·h−1. The difference from the accepted value today is a bit less than 0.02 %.
