How it is calculated
m/s² = g × 9.80665
Multiply the value in standard gravities (g) by 9.80665 to get meters per second squared.
Example
To convert 25 g to meters per second squared: 25 × 9.80665 = 245.166 m/s².

About the units
- 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.
- Meter per second squared
- The SI unit of acceleration: a gain in speed of one meter per second during each second.
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 meters per second squared are in one standard gravity (g)?
1 g = 9.80665 m/s² exactly.
How do I convert standard gravities (g) to meters per second squared?
Use m/s² = g × 9.80665. For example, 25 g = 245.166 m/s².
How many standard gravities (g) are in one meter per second squared?
1 m/s² = 0.101972 g.
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.
