Foot per Second Squared to Standard Gravity (ft/s² to g)
Convert ft/s² to g — Acceleration converter
Also written as ft/s2 to g.
One foot per second squared equals 0.03108095 g, so to convert feet per second squared to g you multiply the value by 0.03108095. A foot per second squared is smaller than a standard gravity — going the other way, 1 g = 32.174049 ft/s². For example, 10 ft/s² = 0.3108095 g and 50 ft/s² = 1.554048 g.
1 ft/s² = 0.03108095 g

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 ft/s² = 0.03108095 g.
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.
