About Foot per second squared (ft/s²)
An imperial unit of acceleration equal to ≈ 0.3048 m/s² per NIST SP 811. ft/s² is the dominant working unit in US vehicle-dynamics analysis (NHTSA crash-test reports per FMVSS-208 and CFR Title 49), military ballistics and weapons-effects research (US Army Ballistic Research Laboratory pre-1991 publications), US aerospace structural testing per MIL-STD-810 (acceleration shock-and-vibration spectra), and US-edition fluid-mechanics / dynamics textbooks (Streeter, Roberson-Crowe, Hibbeler with US-customary tables). Earth's standard gravity expressed in this unit is g = 32.174 ft/s² — which is why US engineering problems and FAA Part 25 transport-aircraft flight-dynamics certification work routinely use the value g = 32.2 (the gravitational constant gc in the F = m·a/gc imperial form that pound-mass / pound-force / ft / s problems require for dimensional consistency). Convert ft/s² to m/s² by multiplying by 0.3048; to g by dividing by 32.174.
About Inch per second squared (in/s²)
An imperial unit of acceleration equal to ≈ 0.0254 m/s² (= 1/12 ft/s²) per NIST SP 811. in/s² is a niche US engineering unit, primarily encountered in: MEMS accelerometer datasheets that dual-list FSR in g and in/s² for older US instrumentation engineers (Analog Devices ADXL series, Honeywell QA-series quartz-flexure sensors, Endevco shock sensors); fine-motion CNC machine-tool servo-loop specifications (Haas, Mazak, Mori Seiki controllers expose axis-acceleration limits in in/s² for legacy programmer-familiarity); vibration-test specifications for small-electronics qualification per MIL-STD-810G method 514 (where g-rms accelerations are sometimes back-calculated in in/s² for spreadsheet workflows); and pre-1990s US-edition machinery-dynamics textbooks. Most modern US engineering has converged on ft/s², g-units, or directly on m/s² for international compatibility. Convert in/s² to m/s² by multiplying by 0.0254; to ft/s² by dividing by 12; to g by dividing by 386.09.
