About these units
Millimeter/Minute (mm/min)
A millimeter per minute is a slow mechanical speed often encountered in CNC machining, automated laboratory equipment, and controlled industrial processes. In medicine, infusion pumps, surgical robotics, and controlled incisions may specify movement in mm/min to maintain safety and precision. By using millimeters instead of centimeters or meters, the unit ensures fine control in delicate operations where even small deviations matter.
Knot (UK) (kt (UK))
The UK knot historically varied slightly from the international knot because the UK used different values for the nautical mile depending on era and maritime authority. Though the differences were minor, they mattered in navigation, where precision affects charting, dead reckoning, and ocean voyaging. Modern UK practice fully aligns with the international knot (1 nautical mile per hour), but historical documents and charts may reference older UK knot values. The knot's rich maritime heritage—used by sailors measuring speed with knotted ropes dragged along the water—makes it one of the oldest continuously used speed units.
