Kilometer/second
A kilometer per second (km/s) is a unit of speed representing the distance of one kilometer traveled in one second.
History/Origin
The kilometer per second has been used in scientific contexts, particularly in astronomy and physics, to measure high velocities such as the speed of celestial objects and spacecraft. Its usage became prominent with the development of precise measurement techniques in the 20th century.
Current Use
Today, km/s is primarily used in astronomy, astrophysics, and space science to describe the velocities of stars, galaxies, and spacecraft. It is also used in scientific research involving high-speed phenomena.
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.
