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.
About Meter per second squared (m/s²)
The SI unit of acceleration (ISO 80000-3 §3-9), equal to a velocity change of exactly one meter per second, each second. m/s² is the universal working unit in physics and engineering — every kinematic equation (v = v₀ + at; x = v₀·t + ½·a·t²), Newton's second law F = m·a, vehicle-dynamics simulation (Carsim, IPG CarMaker, Adams/Car), automotive crash-survivability analysis per FMVSS 208 / Euro NCAP test protocols, building seismic-response analysis per ASCE 7 / Eurocode 8 / NBC, and structural-dynamics vibration analysis (modal analysis, response spectra) uses m/s². Reference values: Earth-surface gravity g = 9.81 m/s² (standard gravity g₀ = 9.80665 m/s² exactly per CIPM 1901); a Tesla Model S Plaid 0-100 km/h acceleration ~12 m/s² (~1.2 g sustained); a Formula 1 car peak lateral 50 m/s² (~5 g cornering); a passenger-aircraft typical climb acceleration 1.5-3 m/s²; an Apollo Saturn V max acceleration ~40 m/s² (~4 g) during second-stage shutdown; the surface acceleration of a 9.0-magnitude megathrust earthquake locally ~10-20 m/s². Smartphone and IMU accelerometers (Bosch BMA / STMicro LIS / InvenSense MPU series) report directly in m/s² or g.
