The knot is a unit of speed equal to one nautical mile per hour, exactly 1.852 km/h. The ISO standard symbol for the knot is kn. The knot is a non-SI unit. The knot is used in meteorology, and in maritime and air navigation. The speeds of vessels relative to the fluids in which they travel (boat speeds and air speeds) are measured in knots.

Feet per second

The foot per second (plural feet per second) is a unit of both speed (scalar) and velocity (vector quantity, which includes direction). It expresses the distance in feet (ft) traveled or displaced, divided by the time in seconds (s). The corresponding unit in the International System of Units (SI) is the metre per second.
