Description

Kilometer per Hour (km/h) in Daily Use

Kilometer per hour (km/h) is a common unit for measuring speed, especially in countries using the metric system. It denotes the number of kilometers traveled in one hour. This unit is prevalent in transportation, with speed limits and vehicle speeds often expressed in km/h. For instance, a car traveling at 100 km/h covers 100 kilometers in one hour.

Mach – The Speed of Sound

Mach is a dimensionless unit representing the ratio of an object's speed to the speed of sound in a given medium, typically air at sea level and 20°C. Mach 1 is equivalent to approximately 343.6 m/s under these conditions. It's commonly used in aerodynamics and aerospace industries to describe supersonic speeds, such as those achieved by fighter jets and spacecraft.
