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 (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.
