Ratio of the speed to the speed of sound [note 1] in the medium (unitless). ≈ 340 m/s in air at sea level ≈ 295 m/s in air at jet altitudes metre per second (SI unit) m/s ≡ 1 m/s = 1 m/s mile per hour: mph ≡ 1 mi/h = 0.447 04 m/s: mile per minute: mpm ≡ 1 mi/min = 26.8224 m/s: mile per second: mps ≡ 1 mi/s = 1 609.344 m/s: speed of ...
Thus, speed over the ground (SOG; ground speed (GS) in aircraft) and rate of progress towards a distant point ("velocity made good", VMG) can also be given in knots. Since 1979, the International Civil Aviation Organization list the knot as permitted for temporary use in aviation, but no end date to the temporary period has been agreed as of ...
Conversion of the Mach unit of speed depends on the altitude at which the speed is measured. That altitude should be specified either in feet (for example, |altitude_ft=10,000 ) or in metres (for example, |altitude_m=3,749 ).
In the United States, it is computed per 100 million miles traveled, while internationally it is computed in 100 million or 1 billion kilometers traveled. According to the Minnesota Department of Public Safety, Office of Traffic Safety Volume of traffic, or vehicle miles traveled (VMT), is a predictor of crash incidence.
For example, = 1013.25 hPa, = 1,225 km/h (661.45 kn). The ratio of specific heats for air is assumed to be 1.4. These formulae can then be used to calibrate an airspeed indicator when impact pressure ( q c {\displaystyle q_{c}} ) is measured using a water manometer or accurate pressure gauge.

Musk, who bought Twitter for $44 billion in 2022, agreed in a 2018 deal with the U.S. Securities and Exchange Commission to get pre-approval from a Tesla lawyer for some tweets.
