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.
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.
