Why do we use knots as a speed measurement unit for air and water travel?
In: Engineering
In olden times, sailors had a rope with knots tied in it every 47ish feet. And they tossed the rope off the side of the boat, and then measured how many “knots” a point of the boat passed in a given period of time. And that was how they measured boat speed in the age of sail, is by counting knots on a rope.
