Acceleration Converter
Convert m/s², ft/s², g-force and km/h per second.
A defined constant, not a local measurement. Actual gravity varies by roughly 0.5% between the poles and the equator.
1 meter per second squared equals 0.101972 standard gravities
About acceleration units
Acceleration is the rate at which speed changes. The SI unit is metres per second squared; vehicle performance is often quoted as the change in km/h or mph per second, and g-force expresses acceleration as a multiple of standard gravity, exactly 9.80665 m/s².
The g unit here means standard gravity, exactly 9.80665 m/s². It is a fixed reference, rather than the changing local gravitational acceleration.
