About these units
Knot (kt)
A knot is equal to one nautical mile per hour, or 1.852 km/h, and is the standard unit of speed in aviation and maritime navigation. Knots are intimately linked to navigation because nautical miles represent distances along Earth's spherical surface. A ship or aircraft traveling at 1 knot moves over one minute of arc of latitude in one hour—reflecting its origins in astronomical navigation. Using knots allows mariners and pilots to integrate seamlessly with charts, headings, coordinate systems, and wind speed conventions. The unit symbolizes centuries of seafaring tradition and remains indispensable for global navigation.
Centimeter/Hour (cm/h)
A centimeter per hour is used in fields where extremely slow processes are tracked, including seepage rates in soil hydrology, chemical diffusion fronts in laboratory experiments, and biological growth in certain organisms. Urban planning and material science may use cm/h to describe settlement rates in soft soils or long-term deformation of structural components. Although rarely used in public communication, cm/h is invaluable in precision scientific contexts where even a centimeter over an hour represents meaningful change.
