About Knot and Miles per Hour
The knot is one nautical mile per hour, exactly 1.852 km/h. Ships, aircraft, and weather charts use knots because the nautical mile maps onto latitude minutes. The mile per hour is exactly 1.609344 kilometers per hour, the road speed unit of the US and UK. Tennis serves, baseball pitches, and hurricane winds are also quoted in mph. One Knot equals 1.150779447 Miles per Hour (1 knot = 1.150779447 mph). Knot to Miles per Hour conversion comes up most often in ship and boat speeds and in aircraft airspeed, typically when figures need restating for US and UK speed limits.
Precision and Rounding: Most speed factors are exact because they derive from exact length and time definitions (1 mph = 1.609344 km/h precisely); Mach is the exception, since the speed of sound varies with temperature and altitude — the figure used here is 343 m/s, the sea-level value at 20 °C. One decimal place covers driving and running; aviation and ballistics carry more.
