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.
Foot/second
Foot per second (ft/s) is a unit of speed representing the distance of one foot traveled in one second.
History/Origin
The foot per second has been used historically in engineering, physics, and aeronautics, originating from the imperial measurement system where the foot is a standard unit of length. Its usage predates the metric system and has been common in the United States and other countries using imperial units.
Current Use
Today, ft/s is primarily used in fields such as physics, engineering, and aviation to measure speeds, especially in contexts where imperial units are standard. It is also used in sports and safety standards related to speed measurements.
