Conversion Formula

µGal = in/s² × 2540000

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 Microgal

The microgal (µGal) equals 10⁻⁸ m/s², the resolution benchmark of the world's most sensitive gravimeters. Earth's gravity varies by about 5.19 × 10⁶ µGal from equator to pole; geodetically meaningful signals - glacial rebound (1-2 µGal/year), groundwater recharge (5-150 µGal), and volcanic inflation (10-200 µGal) - require sub-µGal precision. Superconducting gravimeters achieve noise floors below 0.1 µGal/√Hz; the GRACE-FO satellite pair detected seasonal mass changes of 10-200 µGal over major river basins. 1 µGal = 10⁻⁸ m/s² ≈ 1.02 × 10⁻⁹ g₀.
