About 1.2 mph to the knot

A knot is equal to one minute of a great circle arc per hour. It is an angular measurement, not a linear distance. One degree has sixty minutes of arc, so an object transversing one degree per hour is moving at 60 knots. Nautical miles and knots are used by ships because they operate in a spherical world spanning from outer space to sea level. In theory, if a car traveled mile straight up and down for two total miles, it would travel zero knots since no change of angular motion took place.

A knot is a measure of speed based on the nautical mile, of which there are 1.15 per statute (land) mile... so 1 mph is 1.15 knots. It comes from the practice of using a chip log to quickly determine a ship's speed while underway. ("Chip" referring to a piece of wood, and "log" as in logging the result in a book) A wedge of wood was tied to a rope with knots tied every 47'3" and thrown overboard as somebody turned a 30-second hourglass. They counted how many knots passed by in that time, and that number was how many nautical miles per hour the ship was travelling (the faster they went, the more knots) The distance between knots was chosen so that, in a 30-second period, that number of knots would actually correspond to the speed. It was shorter to say, "Ship's speed 7 knots!" than to say "... seven nautical miles per hour!"

A knot is one nautical mile per hour, so a ship traveling at five knots is traversing five nautical miles per hour. It will tell you everything about it like how they made it up, how they got they got a name, etc. at the site at the bottom. Check it out.

One knot is equal to 1.2mph. So if you are travelling 10knots, this equates to 12mph. Just divide miles per hour by 1.2, or multiply knots by 1.2

A nautical mile is 6076.1 feet.
A statute mile is 5280 feet
The ratio is 6076.1/5280 (mph/kts)
By the way the nautical mile is used because it directly relates to the circumference of the Earth.

It's a nautical mile per hour and I think it's 1.2 mph

1 knot=A nautical mile is equal to about 1.15 survey miles, or 6080 feet.

About a mile per hour. Just a tad faster.
