About these units
Knot (kn). A knot is one nautical mile (exactly 1,852 meters) per hour. It is the standard speed unit in aviation, maritime navigation and meteorology worldwide.
Meter per Second (m/s). Meters per second is the SI derived unit of speed, used in physics and engineering. Wind speeds in meteorology and velocity in science are typically quoted in m/s.
