Answer:
knots are related neutrical term
Although the unit knot does not fit within the SI system, its retention for nautical and aviation use is important because the length of a nautical mile, upon which the knot is based, is closely related to the longitude/latitude geographic coordinate system.

Explanation:
- This method was known as a Dutchman's log. By the late 16th century, sailors had begun using a chip log to measure speed. Afterward, the number of knots that had gone over the ship's stern was counted and used in calculating the vessel's speed. A knot came to mean one nautical mile per hour.
- A knot is one nautical mile per hour (1 knot = 1.15 miles per hour ). The term knot dates from the 17th century, when sailors measured the speed of their ship by using a device called a "common log." This device was a coil of rope with uniformly spaced knots, attached to a piece of wood shaped like a slice of pie.
- The term “knot”, in reference to currents, is defined as one nautical mile per hour and is used to measure speed. A nautical mile is slightly more than a standard mile. ... When the specified time had passed, the line was pulled in and the number of knots on the rope between the ship and the wood were counted.
- The global coordinate system defines the position and translation of a body in space. Local coordinate systems define how limbs and body segments articulate about joints. To achieve uniform motion in DHMs, coordinate systems must be either communicated in protocols or standardized.
