Kilometer/hour
Kilometer per hour (km/h) is a unit of speed expressing the number of kilometers traveled in one hour.
History/Origin
The km/h unit originated from the metric system, developed in France during the late 18th century, and became widely adopted for measuring speed in transportation and scientific contexts.
Current Use
Km/h is commonly used worldwide to specify vehicle speeds, speed limits, and other applications involving the measurement of speed in everyday life and transportation systems.
Yard/second
Yard per second (yd/s) is a unit of speed representing the distance of one yard traveled in one second.
History/Origin
The yard has been used as a unit of length since the 12th century, primarily in the UK and the US. The yard/second as a speed unit emerged with the adoption of the yard in measurement systems, but it is less common than other units like meters per second.
Current Use
Yard per second is occasionally used in fields such as aviation, sports, and engineering within the United States and the UK for measuring speeds where imperial units are preferred.
