Yard/hour
Yard per hour (yd/h) is a unit of speed representing the distance of one yard traveled in one hour.
History/Origin
The yard has been a traditional unit of length in the imperial and US customary systems, and units like yard per hour have historically been used for measuring slow speeds, especially in contexts like textiles and manufacturing. Its usage has declined with the adoption of metric units.
Current Use
Yard per hour is rarely used today, primarily in specialized or historical contexts. It may still be referenced in certain industries or for conversions involving imperial units, but it is largely replaced by metric units such as meters per second or kilometers per hour.
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.
