About these units

Millimeter/Hour (mm/h)

A millimeter per hour is extraordinarily slow, used in geology, meteorology, and materials science to measure phenomena like soil creep, tectonic plate micro-motion, or extremely light precipitation (drizzle). In manufacturing, mm/h may describe slow deposition rates in thin-film fabrication or high-precision milling processes. Despite seeming negligible, speeds measured in mm/h can accumulate into significant changes over weeks, months, or years—making them essential for long-term studies.

Speed of Sound in Sea Water (vₛₑₐ)

In sea water, the speed of sound is generally higher—around 1,530–1,540 m/s—due to dissolved salts, temperature gradients, and pressure at depth. Sea water's complex structure causes refraction of sound waves, creating deep sound channels (like the SOFAR channel) that allow sound to travel vast distances with minimal attenuation. Oceanographers use sound-speed profiles to map underwater topography, measure ocean temperatures, and study global climate patterns. The speed of sound in sea water is essential for both marine ecology and military navigation.
