What is a Knot?
A knot is a unit of speed measurement used predominantly in maritime and aviation contexts. It is employed extensively in the fields of nautical navigation and scuba diving. The term “knot” is derived from the practice of counting the number of knots on a log line that unspooled from a ship over a specific period of time, which provided a measure of the ship’s speed. Today, the knot is defined as one nautical mile per hour and serves as a valuable metric for scuba divers and watercraft operators alike.
