About Inches per second squared
The inch per second squared (in/s²) equals exactly 0.0254 m/s², used in US customary engineering for machine tool acceleration, CNC linear stages, and vibration testing. Standard gravity is g₀ = 386.089 in/s², a constant embedded in US dynamics software (ANSYS, Nastran) configured with US customary units. High-performance linear motor stages reach 500-2000 in/s². 1 in/s² = 0.0254 m/s² ≈ 2.59 × 10⁻³ g₀.
About Feet per second squared
The foot per second squared (ft/s²) equals exactly 0.3048 m/s², the coherent acceleration unit in the imperial engineering system where F [lbf] = m [slug] × a [ft/s²]. Standard gravity is g₀ = 32.174 ft/s², a constant used throughout US aerospace and structural engineering - from legacy NACA reports to modern software (SAP2000, ETABS with US units). A car braking at 0.8 g decelerates at about 25.7 ft/s². 1 ft/s² = 0.3048 m/s² ≈ 3.108 × 10⁻² g₀.
