- Swap the direction to convert back, or copy the result.
How it is calculated
g = ft/s² × 0.03108095017
Multiply the value in feet per second squared by 0.03108095017 to get standard gravities (g).
Example
To convert 25 ft/s² to standard gravities (g): 25 × 0.03108095017 = 0.777024 g.

About the units
- Foot per second squared
- A gain in speed of one foot per second each second, exactly 0.3048 m/s². It is used in US engineering.
- Standard gravity (g)
- Standard gravity g is exactly 9.80665 m/s², set by the General Conference on Weights and Measures. It is used to express the g-force felt by pilots and car passengers.
Limits and caveats
- Results are rounded for display and computed with the browser's floating point precision (about 15 significant digits).
- Both unit factors are exact by their official definitions.
Questions about this tool
How many standard gravities (g) are in one foot per second squared?
1 ft/s² = 0.031081 g exactly.
How do I convert feet per second squared to standard gravities (g)?
Use g = ft/s² × 0.03108095017. For example, 25 ft/s² = 0.777024 g.
How many feet per second squared are in one standard gravity (g)?
1 g = 32.174 ft/s².
How many m/s² is 1 g?
1 g is exactly 9.80665 m/s², a fixed standard value. Real gravity varies slightly with latitude and altitude, from about 9.78 at the equator to 9.83 at the poles.
How do I get a car's acceleration from its 0 to 100 km/h time?
Divide 100 by the seconds to get km/h per second, then convert to m/s². For example 10 seconds means 10 km/h per second, about 2.78 m/s² or 0.283 g on average.
