0.44704. Miles per hour (mph, m.p.h., MPH, or mi/h) is a British imperial and United States customary unit of speed expressing the number of miles travelled in one hour. It is used in the United Kingdom, the United States, and a number of smaller countries, most of which are UK or US territories, or have close historical ties with the UK or US.
True airspeed. An analog true airspeed indicator for an airplane. The pilot sets the pressure altitude and air temperature in the top window using the knob; the needle indicates true airspeed in the lower left window. Here the speed is displayed both in knots (kn) and miles per hour (mph). The true airspeed (TAS; also KTAS, for knots true ...
The knot (/ nɒt /) is a unit of speed equal to one nautical mile per hour, exactly 1.852 km/h (approximately 1.151 mph or 0.514 m/s). [1][2] The ISO standard symbol for the knot is kn. [3] The same symbol is preferred by the Institute of Electrical and Electronics Engineers (IEEE), while kt is also common, especially in aviation, where it is ...
Indicated airspeed (IAS) is the airspeed of an aircraft as measured by its pitot-static system [1] and displayed by the airspeed indicator (ASI). [2] This is the pilots' primary airspeed reference. This value is not corrected for installation error, instrument error, or the actual encountered air density, [2] being instead calibrated to always ...
Beaufort scale. A ship in a force 12 (" hurricane -force") storm at sea, the highest rated on the Beaufort scale. The Beaufort scale / ˈboʊfərt / is an empirical measure that relates wind speed to observed conditions at sea or on land. Its full name is the Beaufort wind force scale.

In practice, most U.S.-market vehicles have mile odometers and dual-labeled speedometers with miles-per-hour as the primary calibration. Some 2000s era Buicks have a single speed gauge with a button on the instrument panel to switch the scale between MPH and km/h. Other vehicles have digital speedometers which can be set to read out speeds in ...
The maximum speed for the Saturn V rocket was 25,000 mph. The maximum speed of a Bugatti Chiron (the fastest production road car) is 305 mph. The Mitubishi Mirage (the cheapest car available in ...
