Conversion Formula
µGal = kn/s × 51444444.44
About Knots per second
The knot per second (kn/s) equals 1852/3600 m/s² ≈ 0.5144 m/s², used in aviation and maritime operations where speed is measured in knots. Aircraft carrier catapult launches accelerate an F/A-18 from 0 to ~150 kn in 2-2.5 s, giving 60-75 kn/s ≈ 31-39 m/s². A commercial jet rejected takeoff from V1 (~145 kn) to rest in ≈25 s decelerates at 5-6 kn/s ≈ 2.6-3.1 m/s². 1 kn/s = 463/900 m/s² ≈ 5.25 × 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.
