Foot/minute
Foot per minute (ft/min) is a unit of speed representing the number of feet traveled in one minute.
History/Origin
The foot per minute has been used historically in engineering and construction to measure speed, especially in contexts where imperial units are standard. Its usage predates the widespread adoption of metric units.
Current Use
Today, ft/min is primarily used in fields such as HVAC, ventilation, and certain engineering applications to measure airflow or movement speed where imperial units are preferred.
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.
