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.
About Gal
The gal (Gal) equals 1 cm/s² = 0.01 m/s², named after Galileo Galilei in recognition of his free-fall experiments. Earth's surface gravity is approximately 980 Gal; the GRS80 normal gravity formula gives 978.03 Gal at the equator and 983.22 Gal at the poles. The BIPM SI Brochure recognises the Gal as a non-SI unit accepted in geophysics. 1 Gal = 0.01 m/s² = 1 cm/s² = 1000 mGal ≈ 1.02 × 10⁻³ g₀.
