Conversion Formula

µGal = mph/s × 44704000

About Miles per hour per second

The mile per hour per second (mph/s) equals exactly 0.44704 m/s², the natural acceleration unit for road vehicles in the US and UK where speed is measured in mph. A 0-60 mph time of 2.0 s (Tesla Model S Plaid) gives 30 mph/s ≈ 13.4 m/s²; a typical family car at 8.5 s gives 7.1 mph/s ≈ 3.2 m/s². Emergency braking for Amtrak trains requires at least 26 mph/s ≈ 11.6 m/s². 1 mph/s = 0.44704 m/s² (exact) ≈ 4.56 × 10⁻² 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.
