Mach (20°c, 1 Atm)

Mach is a unit of speed representing the ratio of an object's speed to the speed of sound in the surrounding medium, typically at 20°C and 1 atm pressure.

History/Origin

Named after physicist Ernst Mach, the Mach number was developed in the early 20th century to describe speeds relative to the speed of sound, especially in aeronautics and fluid dynamics.

Current Use

Mach is widely used in aeronautics and astronautics to express aircraft and spacecraft speeds, particularly in high-speed flight and supersonic travel contexts.


Millimeter/hour

Millimeter per hour (mm/h) is a unit of measurement that indicates the rate of rainfall or precipitation, representing how many millimeters of water fall in one hour.

History/Origin

The millimeter per hour has been used in meteorology and hydrology to quantify rainfall intensity, especially with the advent of precise rain gauges and weather measurement tools in the 20th century.

Current Use

Today, mm/h is commonly used in weather forecasting, climate studies, and hydrological assessments to measure and communicate the intensity of rainfall events.
