About Knots
The knot is a unit of speed equal to one nautical mile per hour. It is used in maritime and aviation navigation worldwide. One knot equals approximately 1.852 km/h.
Real-World Examples
- A typical cruise ship travels at 20 to 24 knots
- A commercial aircraft cruises at about 450 to 575 knots
- Wind speed in weather forecasts for mariners is given in knots
💡 Did you know? The word 'knot' comes from an old method of measuring ship speed: sailors would throw a rope with knots tied at regular intervals overboard and count how many knots passed through their hands in a fixed time.
About Feet per second
Feet per second is an imperial unit of speed used primarily in ballistics, engineering calculations, and some aviation contexts in the United States.
Real-World Examples
- The muzzle velocity of a typical rifle bullet is about 2,500 feet per second
- A baseball thrown at 90 mph travels at 132 feet per second
- Sound travels at approximately 1,125 feet per second in air
💡 Did you know? In ballistics, the speed of a bullet is almost always measured in feet per second (fps), even in countries that use the metric system.
