Feet per second (ft/s)
Definition
Feet per second (ft/s or fps) is an imperial unit of speed measuring the number of feet traveled in one second. 1 ft/s ≈ 0.3048 m/s.
History
Feet per second has been used in ballistics and engineering since the development of firearms and artillery. It was a natural unit in the foot-pound-second (FPS) system widely used in British and American engineering.
Current use
Feet per second is commonly used in ballistics (bullet velocity), engineering calculations in the US, water flow measurements, and some HVAC applications. It appears frequently in American technical specifications.
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.
