Foot per second to Knot Converter

Foot per second (ft/s) is a unit of speed expressing the number of feet traveled in one second. It provides more precise speed measurements in imperial systems and is commonly used in engineering and scientific applications within imperial unit systems.

Foot per second developed as a more precise alternative to mile per hour for engineering and scientific applications in imperial systems. It provided appropriate scaling for applications requiring finer speed resolution than mph could practically provide.

Ft/s is used in engineering calculations, ballistics, fluid dynamics, and scientific applications within imperial systems. It's standard for projectile velocities, fluid flow rates, and engineering applications requiring precise speed measurements in imperial units.

A knot (kn) is a unit of speed equal to one nautical mile per hour, approximately 1.852 kilometers per hour. It's the standard speed unit for maritime and aviation navigation, based on the Earth's geometry and navigation principles.

The knot originated from maritime navigation practices where speed was measured by counting knots on a rope trailing behind a ship. It became formalized as one nautical mile per hour and was adopted as the international standard for maritime and aviation speed measurements.

Knots are universally used in maritime navigation, aviation, meteorology (wind speeds), and oceanography. They're standard for ship speeds, aircraft speeds, wind velocity reporting, and all navigation applications where geographic positioning is important.
