About these units
Centimeter/Second (cm/s)
A centimeter per second is widely used in hydrology, biology, and physics to measure modest fluid flows, blood velocities, small organism movement, or lab-scale chemical transport. In medicine, cm/s is important in Doppler ultrasound, where blood flow speeds in arteries and veins are routinely measured. In physical sciences, cm/s appears in low-speed fluid mechanics experiments, sediment transport studies, and oceanographic microcurrent analysis. It offers a convenient, human-comprehensible scale for small but dynamic systems.
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 Modern UK practice fully aligns with the international knot (1 nautical mile per hour), but historical documents and charts may reference older UK knot values.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.
