About these units
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.
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.
