About these units
Mach (SI Standard) (Ma)
Mach is a dimensionless measure of speed relative to the speed of sound in a given medium. Mach 1 corresponds to the speed of sound, Mach 2 is twice that speed, and so on. Mach values change with temperature, atmospheric pressure, and altitude because the speed of sound changes with these conditions. Aircraft performance, supersonic flight, rocket design, and shockwave analysis all depend heavily on Mach numbers. Mach is more than just a speed measure—it categorizes aerodynamic regimes: Subsonic (Mach < 1), Transonic (Mach 0.8–1.2), Supersonic (Mach 1–5), Hypersonic (Mach > 5). Mach numbers therefore provide insight into aerodynamic behavior, not just velocity.
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.
