- knot
- A unit of speed. While the knot is commonly used in aviation and other contexts as an abbreviation of nautical miles per hour, in soaring the knot is also used to describe lift (and sink conditions). Using approximations, one knot of upward velocity in a thermal equates to roughly 100 feet per minute of climb.
