Standard Gravity to Foot per Second Squared (g to ft/s²)
Convert g to ft/s² — Acceleration converter
Also written as g to ft/s2.
One standard gravity equals 32.174049 ft/s², so to convert g to feet per second squared you multiply the value by 32.174049. A standard gravity is larger than a foot per second squared — going the other way, 1 ft/s² = 0.03108095 g. For example, 10 g = 321.740486 ft/s² and 50 g = 1608.7 ft/s².
1 g = 32.174049 ft/s²

Standard gravity is a defined constant
Standard gravity is a defined constant, not a measurement: g₀ = 9.80665 m/s² exactly, fixed by the 3rd CGPM in 1901. Every conversion between g and metric or imperial acceleration units on this page uses that exact figure. Local gravity varies by roughly ±0.3% with latitude and altitude, so a precise local value will differ slightly from the standard one.
Expressing acceleration in g is a convention, not a separate physical quantity — it simply reports acceleration as a multiple of g₀. On this page, 1 g = 32.174049 ft/s².
Context for the numbers: a passenger car braking hard reaches roughly 1 g, a commercial airliner takes off at well under 0.5 g, and sustained exposure above about 5 g requires training and equipment.
