About this calculator
Standard gravity is defined as exactly 9.80665 m/s². Expressing acceleration in g makes it easy to judge whether a force is gentle or extreme.

Method and assumptions
Formula basis and scope
Convert acceleration via metres per second squared; standard gravity = 9.80665 m/s².
Only the displayed unit definitions are converted; rounding and measurement uncertainty are separate.

Disclaimer
These calculators give general conversion results. Rounding and the precision of the value you enter both affect the output, so treat displayed decimals as indicative rather than exact.

Frequently asked questions
Why is one standard gravity fixed at 9.80665 m/s²?
Standard gravity is a defined constant, not a measurement of your location, set at exactly 9.80665 m/s² by international agreement. Expressing a car's 0.3 g launch or a roller coaster's 4 g pull in g divides the acceleration by that fixed number. Local gravity varies a few hundredths of a percent with latitude and altitude, which this converter ignores.
