Why do boats use knots instead of mph?

Cars and trains, known for shorter travel segments, use miles per hour or kilometers per hour. Boats and planes, which often travel longer distances affected by the earth’s curvature, use knots. Knots are a more accurate way of predicting how a boat (or a plane) traverses the face of the earth.

Why do sailors 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.
