Why wind speed on land is measured in mph while wind speed on the ocean is measured in kn(ots)
Using knots as a measurement makes sense on the ocean. 1 knot is 1 nautical mile per hour. 1 nautical mile also represents one minute of longitude at the equator.
The Short Answer
Using knots as a measurement makes sense on the ocean. 1 knot is 1 nautical mile per hour. 1 nautical mile also represents one minute of longitude at the equator. When sailing was easier to use knots to determine distance traveled when using a chart. One degree of longitude is 60 nautical miles at the equator. The math gets a bit more complex away from the equator, but If I know my latitude, and know I have to travel 5 degrees east, I can calculate the distance required to go in knots much easier. Knots are not needed today with GPS and all the other technology, but due to tradition it is still used. Also, the way to determine speed originally was to throw a piece of wood or something overboard with a rope attached to it. You would have a knot tied at certain intervals, and you would count how many knots passed through your hand in 30 seconds.
