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 Inches per second squared

The inch per second squared (in/s²) equals exactly 0.0254 m/s², used in US customary engineering for machine tool acceleration, CNC linear stages, and vibration testing. Standard gravity is g₀ = 386.089 in/s², a constant embedded in US dynamics software (ANSYS, Nastran) configured with US customary units. High-performance linear motor stages reach 500-2000 in/s². 1 in/s² = 0.0254 m/s² ≈ 2.59 × 10⁻³ g₀.
