Centimeter/hour
Centimeter per hour (cm/h) is a unit of speed that measures the distance in centimeters traveled or covered in one hour.
History/Origin
The centimeter per hour has been used primarily in scientific and industrial contexts to measure slow rates of movement or growth, especially in fields like biology and material science. Its usage became more standardized with the adoption of the metric system in the 19th century.
Current Use
Today, cm/h is used in applications such as measuring the rate of biological growth, sedimentation, or the movement of fluids and materials in scientific research and engineering.
Mach (Si Standard)
The Mach number is a dimensionless unit representing the ratio of an object's speed to the speed of sound in the surrounding medium.
History/Origin
Named after the Austrian physicist Ernst Mach, the Mach number was introduced in the early 20th century to describe supersonic and hypersonic speeds, initially used in aerodynamics and fluid dynamics research.
Current Use
The Mach number is widely used in aeronautics and astronautics to specify aircraft and spacecraft speeds relative to the local speed of sound, especially in high-speed flight regimes.
