About Standard gravity
Standard gravity (g₀) is defined as exactly 9.80665 m/s² by the 3rd CGPM (1901), chosen to approximate surface gravity at ~45.5° latitude. It is the universal reference for human g-tolerance: fighter pilots sustain up to +9 g₀ with G-suit; sustained +3 g₀ causes greyout unprotected; F1 drivers experience +5 g₀ lateral and -4 g₀ braking. Pound-force is defined as 0.45359237 kg × g₀ = 4.44822 N (exact). Rocket specific impulse in seconds = thrust / (mass flow × g₀). 1 g₀ = 9.80665 m/s² = 980.665 Gal ≈ 32.174 ft/s² ≈ 35.304 km/h/s.
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.
