Conversion Formula

m/s² = Gal × 0.01

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.

About Metres per second squared

The metre per second squared (m/s²) is the SI coherent derived unit of acceleration, defined as Δv/Δt (m/s per s). It makes Newton's second law F = ma dimensionally consistent with the newton (1 N = 1 kg·m/s²). Key reference values: standard gravity g₀ = 9.80665 m/s² (exact); ISS centripetal acceleration ≈ 8.68 m/s²; Falcon 9 max axial load ≈ 49 m/s² (5 g₀); human tolerance limit for sustained acceleration ≈ 30 m/s². All SI engineering and simulation software uses m/s² as the native acceleration unit. 1 m/s² = 100 Gal ≈ 0.102 g₀ ≈ 3.281 ft/s².
