Foot/second
Foot per second (ft/s) is a unit of speed representing the distance of one foot traveled in one second.
History/Origin
The foot per second has been used historically in engineering, physics, and aeronautics, originating from the imperial measurement system where the foot is a standard unit of length. Its usage predates the metric system and has been common in the United States and other countries using imperial units.
Current Use
Today, ft/s is primarily used in fields such as physics, engineering, and aviation to measure speeds, especially in contexts where imperial units are standard. It is also used in sports and safety standards related to speed measurements.
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.
