Mile/hour
The mile per hour (mph) is a unit of speed commonly used in the United States and the United Kingdom to measure the speed of vehicles. It indicates the number of miles traveled in one hour. This unit is prevalent in transportation and is used on road signs and vehicle speedometers in countries where the imperial system is used.
Mach (SI standard)
The Mach number (Mach) is a dimensionless unit used to express the speed of an object relative to the speed of sound in the surrounding medium. A Mach number of 1 indicates the speed of sound, with higher numbers representing supersonic or even hypersonic speeds. This unit is critical in aerodynamics and aerospace engineering.
