About Kilometres per second squared

The kilometre per second squared (km/s²) equals 1000 m/s², useful in astrodynamics where velocities are naturally in km/s. Solar system surface gravities: Earth ≈ 9.807 × 10⁻³ km/s², Moon ≈ 1.62 × 10⁻³ km/s², Jupiter ≈ 0.0248 km/s², Sun ≈ 0.274 km/s². Spacecraft trajectory simulators (GMAT, STK) express perturbation accelerations in km/s² through the equation of motion ā = -μr/r³ + δa_perturb. Ion engine thrust on a 600 kg probe (8 mN) gives ≈ 1.3 × 10⁻⁸ km/s². 1 km/s² = 1000 m/s² ≈ 101.97 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.
