Knots (kn)
Definition
A knot (kn) is a unit of speed equal to one nautical mile per hour (approximately 1.852 km/h or 1.151 mph). It is derived from maritime navigation practices.
History
The knot originated from a 17th-century method of measuring ship speed by counting knots on a rope paid out over a fixed time from a 'chip log'. The practice gave rise to the unit name that persists today.
Current use
Knots are the standard speed unit in maritime and aviation navigation worldwide. Air traffic control, ship navigation, weather reports for marine and aviation use, and ocean current speeds all use knots.
Kilometers per hour (km/h)
Definition
Kilometers per hour (km/h or kph) is a metric unit of speed expressing the number of kilometers traveled in one hour. 1 km/h ≈ 0.2778 m/s.
History
Kilometers per hour became widely used in the 20th century as road networks expanded globally. Most countries adopted km/h for speed limits during the metrication movements of the 1960s–1980s.
Current use
Kilometers per hour is the standard unit for road speed limits and vehicle speedometers in most countries worldwide (except the US, UK, and a few others). It is also used in weather reports for wind speed in many nations.
