## What is knot?

The **knot** is a non-SI unit of speed equal to one international nautical mile per hour or approximately 0.514444 meters per second (1 kn = 0.514444 m/s), the derived unit of speed in the International System of Units (SI). It is also equal to about 1.852 kilometers per hour (km per h), or 1.150779 miles per hour (mph or mi/h) or 1.68781 feet per second (ft/s).

The knot is used worldwide in nautical and air navigation and in meteorology.
