Convert from speed of sound [air] to knot

Unit Definition (speed of sound [air])
The speed of sound c (from Latin celeritas, "velocity") varies depending on the medium through which the sound waves pass. It is usually quoted in describing properties of substances (e.g. see the article on sodium).

Unit Definition (knot)
The Knot is common unit of velocity or speed, which is mostly referred to at sea as a measurement of boat, wind or water current velocity. One Knot is equal to one nautical mile per hour. The word comes from a former method of measuring a ship's speed, which used a knotted cord called the log line.
