How it is calculated
m/s² = km/h/s × 0.2777777778
Multiply the value in kilometers per hour per second by 0.2777777778 to get meters per second squared.
Example
To convert 25 km/h/s to meters per second squared: 25 × 0.2777777778 = 6.94444 m/s².

About the units
- Kilometer per hour per second
- A gain of 1 km/h in speed each second, exactly 1/3.6 m/s². It helps read car 0 to 100 km/h times.
- 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 kilometer per hour per second?
1 km/h/s = 0.277778 m/s² exactly.
How do I convert kilometers per hour per second to meters per second squared?
Use m/s² = km/h/s × 0.2777777778. For example, 25 km/h/s = 6.94444 m/s².
How many kilometers per hour per second are in one meter per second squared?
1 m/s² = 3.6 km/h/s.
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.
