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 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.
