About Acceleration Conversions
Acceleration measures how quickly velocity changes over time. The SI unit is metres per second squared (m/s²); a dropped object in Earth's atmosphere accelerates at roughly 9.8 m/s², the value codified as standard gravity g₀ = 9.80665 m/s² by the CGPM in 1901 and used today in the definitions of the pound-force and the kilogram-force. The foot per second squared (ft/s²) is the US-customary counterpart, with 1 ft/s² equal to exactly 0.3048 m/s². Car spec sheets rarely list acceleration directly but imply it: a 0–60 mph run in 3.0 seconds averages about 8.94 m/s², or 0.91 g. Aerospace engineers state sustained g-loads in multiples of g₀: a modern fighter endures 9 g in hard turns, Space Shuttle launches peaked near 3 g. Geophysicists measure tiny gravitational anomalies in gals (1 cm/s²) and milligals. Our converter respects these exact definitions so engineering calculations, crash safety work, and seismology reports stay coherent.
