Short background on the units used in this conversion.
Standard gravity (g) is exactly 9.80665 m/s² — the nominal acceleration due to gravity at Earth’s surface, used as a reference in engineering.
Multiples of g express fighter-jet maneuvers, centrifuge ratings, and shock loads relative to everyday gravitational acceleration.
The foot per square second (ft/s²) is an imperial acceleration unit equal to 0.3048 m/s².
Feet per square second appear in US automotive, aerospace, and ballistics references when speeds are given in feet per second.
ft/s² = g × 32.1740485564g = ft/s² × 0.0310809502, using the same exact factors as this converter.Jump to any acceleration conversion starting from acceleration of gravity — including the reverse direction and every other unit in our dataset.
