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.
Foot/hour
Foot per hour (ft/h) is a unit of speed representing the distance of one foot traveled in one hour.
History/Origin
The foot per hour has historically been used in engineering and construction to measure slow speeds, especially in contexts where imperial units are standard. Its usage has declined with the adoption of metric units and more common speed measurements like meters per second or miles per hour.
Current Use
Today, foot per hour is rarely used in practical applications but may still appear in specialized fields such as certain engineering, construction, or scientific contexts where imperial units are maintained.
