Kilometer/hour
The kilometer per hour (km/h) is a unit of speed commonly used to express the velocity of vehicles, such as cars and trains. It indicates how many kilometers an object travels in one hour. This unit is widely used in everyday life, especially in transportation and speed limit regulations.
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.
