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.
Knot (Uk)
A knot (kt) is a unit of speed equal to one nautical mile per hour, commonly used in maritime and aviation contexts.
History/Origin
The knot originated in the 17th century as a measure for sailors to estimate their speed using a device called a chip log, which involved counting the number of knots that passed through a sailor's hands over a specific time interval. It became standardized as a nautical speed unit over time.
Current Use
Today, the knot is primarily used in maritime and aviation industries worldwide to measure vessel and aircraft speeds, maintaining its historical significance and practical application.
