maratoolHow to convert m/s² to g-force
Type an acceleration — read m/s², g, ft/s², Gal, or mph/s instantly.
Accelerometer datasheets read g, physics problems read m/s², and US dynamics texts read ft/s². The Acceleration Converter converts between them using the exact standard-gravity definition.
How it works
- Pick units — "Standard gravity (g)" to "Meter per second squared (m/s²)", or any other pair.
- Type a value — the result updates as you type, with swap and copy.
- Copy — one click, with "Copied!" feedback.
Acceleration conversion factors
Every unit converts through the meter per second squared (the base unit). To convert A → B, multiply by A's factor and divide by B's:
| Unit | = this many meter per second squareds |
|---|---|
| Meter per second squared (m/s²) | 1 |
| Standard gravity (g) | 9.80665 |
| Foot per second squared (ft/s²) | 0.3048 |
| Gal / centimeter per second squared (Gal) | 0.01 |
| Kilometer per hour per second (km/h·s) | 0.277777777778 |
| Mile per hour per second (mph/s) | 0.44704 |
When you need it
Reference points: free fall is 1 g (9.80665 m/s² exactly), a hard car brake is about 1 g, fighter-jet turns reach 9 g, and a smartphone accelerometer typically ranges ±2 g to ±16 g.
Sources & methodology
Conversion factors follow NIST Special Publication 811; exact-by-definition factors are marked in the tool itself. All math runs client-side in your browser — nothing is uploaded.
