One knot equals one nautical mile per hour, or roughly 1.15 statute mph.

Why do we use knots instead of mph?

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.

Why is a nautical mile different than a mile?

(Its length has varied considerably at different periods and in different localities; the legal mile is now 1,760 yards, or 5,280 feet.) Such a linear measurement cannot be used at sea, so the nautical mile is based on the length of one minute of arc (or 1/60 of a degree) of a great circle of Earth.

Why is boat speed in knots?

Boats & Planes calculate speed in knots because it is equal to one nautical mile. Nautical miles are used because they are equal to a specific distance measured around the Earth. Since the Earth is circular, the nautical mile allows for the curvature of the Earth and the distance that can be traveled in one minute.
