About Milligal
The milligal (mGal) equals 10⁻⁵ m/s², the standard unit for geophysical gravity surveys. Bouguer gravity anomalies - reported in mGal after latitude and terrain corrections - reveal subsurface density contrasts: salt domes give +5 to +50 mGal, oceanic spreading ridges -200 to -300 mGal. Standard gravity is ≈ 980 765 mGal at sea level. The International Gravity Reference Frame 2016 is tied to absolute stations accurate to 0.01 mGal. 1 mGal = 10⁻⁵ m/s² ≈ 1.02 × 10⁻⁶ 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.
