About these units
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.
Foot/Hour (ft/h)
A foot per hour is almost comically slow, yet still relevant in specific technical fields. Pipeline corrosion creep, structural deformation, glacial shifts, and certain chemical processes may be measured in ft/h when imperial units are required. While practically invisible to human perception, speeds expressed in ft/h become meaningful over long intervals, providing insight into incremental natural or mechanical change.
