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 Centimeter per second squared (cm/s²)

A CGS (centimeter-gram-second) unit of acceleration equal to exactly 0.01 m/s². Also formally called the 'Gal' (named for Galileo Galilei, originator of mathematical free-fall analysis ~1604), with the symbol 'Gal' used in published scientific notation. cm/s² / Gal is the standard working unit in gravimetry, geodesy, and Earth-physics research: regional variations in Earth's gravity field are reported in milligals (mGal = 10⁻³ Gal); high-precision spring gravimeters (LaCoste-Romberg, Scintrex CG-5/CG-6) and superconducting gravimeters (GWR Instruments iGrav) resolve microgals (µGal = 10⁻⁶ Gal); the GOCE / GRACE / GRACE-FO satellite missions map Earth's gravity field to a few µGal globally. Used in geophysical surveying to locate subsurface oil reservoirs (anomalies ~1-50 mGal), mineral deposits, underground voids and caverns, archaeological-feature mapping, and groundwater-table tracking. Earth-surface gravity variation between equator and pole is ~5,200 mGal (5.2 Gal), and free-air gradient is -3.09 µGal/cm of altitude.
