History: The knot originated from the practice of measuring ship speed using a rope with knots at intervals. The nautical mile is based on the Earth's circumference. The knot remains standard in navigation.
Current use: Knots are used for ship speed, aircraft speed, and wind speed in marine and aviation. Weather reports for sailors use knots. One knot ≈ 1.15 mph.

km/h (kmh)

Definition: Kilometers per hour (km/h) is a unit of speed. It measures distance traveled in kilometers per hour. It is the standard speed unit in most countries and for vehicles worldwide.
History: km/h became standard with the metric system. It is used on speedometers in most countries. Road signs and speed limits use km/h except in the US and UK.
Current use: km/h is used for vehicle speed, wind speed, and athletic performance. Speed limits and odometers use km/h in metric countries. 100 km/h ≈ 62 mph.
