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.
Millimeter/second
Millimeter per second (mm/s) is a unit of speed representing the distance of one millimeter traveled in one second.
History/Origin
The millimeter per second has been used in scientific and engineering contexts to measure small-scale velocities, especially in fields like fluid dynamics and material science, as a standard unit derived from the metric system.
Current Use
Today, mm/s is commonly used in scientific research, engineering, and technical applications to quantify low velocities, such as in microfluidics, biomechanics, and precision manufacturing.
