One knot equals one nautical mile per hour, or roughly 1.15 statute mph.
Why do we use knots instead of miles per hour?
Therefore, in the aviation and nautical worlds, knots are oftentimes used in place of MPH and KPH since they are easier to navigate with. Unlike statute – or land based – miles, nautical miles are based directly on the Earth’s degree of latitudes. One nautical mile equates exactly to one minute of latitude.
