Acceleration Calculator
Convert acceleration between meters per second squared, feet per second squared, and g-force. Enter a signed acceleration value and the calculator returns the selected target unit plus the equivalent values in every supported unit. It is useful for physics problems, vehicle launch figures, braking estimates, elevator motion, and translating specifications written in different unit systems.
How to use this calculator
- Enter the Value in the current acceleration unit.
- Choose From unit as m/s², ft/s², or g.
- Choose To unit and read the converted acceleration.
Negative values are allowed, so the same form can describe slowing down or acceleration in the opposite direction. If your source data is speed over time, convert speed first with the speed converter, then use consistent time units.
Conversion formula
acceleration = change in velocity / change in time
The converter uses m/s² as its base unit:
To convert, multiply by the source factor to get m/s², then divide by the target factor. For example, 9.80665 m/s² divided by 9.80665 equals exactly 1 g. The same value is about 32.1740 ft/s².
Quick reference
| Acceleration | Equivalent |
|---|---|
| 1 ft/s² | 0.3048 m/s² |
| 1 g | 9.80665 m/s² |
| 1 m/s² | 0.101972 g |
Acceleration connects directly to force through mass times acceleration, so the force converter is helpful when translating newtons, pound-force, and kilogram-force. For vertical motion, the vertical-speed calculator can provide additional context.
