What is Knot ?

A Knot is a unit of speed primarily used in maritime and aviation contexts. It represents the speed at which a vessel or aircraft travels through water or air, respectively. One knot is equal to one nautical mile per hour, which translates to about 1.852 kilometers per hour or approximately 1.15078 miles per hour.

Historically, a knot was determined by counting the number of knots in a rope that unraveled from a reel over a specific time interval while a ship was underway. This method gave sailors a way to estimate their speed based on how quickly the knots passed through their hands.

Today, knots are still widely used in navigation, sailing, and aviation to measure speed over water or through the air, offering a standardized unit that remains crucial for safety and operational efficiency.
