What this tool does
Calculate acceleration instantly in your browser — the published formula, worked locally with no data sent anywhere. Constant (average) acceleration only — if the acceleration varies, this is the mean over the interval. Velocities are signed: use negative values for motion in the opposite direction.
How to use the Acceleration Calculator
- Enter or select initial velocity (m/s).
- Enter or select final velocity (m/s).
- Enter or select time (s).
- Read the calculated result; change any measurement to compare alternatives.
Formula
average acceleration a = (v − u) / t; distance covered s = ½(u + v)·t (the SUVAT relation for constant acceleration).

- Initial velocity (m/s)
- v1

Constant (average) acceleration only — if the acceleration varies, this is the mean over the interval. Velocities are signed: use negative values for motion in the opposite direction.
Worked example
For acceleration calculator, the following measurements illustrate the exact method: Initial velocity (m/s): 0; Final velocity (m/s): 20; Time (s): 5.
Inputs
- Initial velocity (m/s)0
- Final velocity (m/s)20
- Time (s)5
Result
- Acceleration (m/s²)4
- Acceleration (ft/s²)13.12
- Acceleration in g0.41
- Change in velocity (m/s)20
- Distance covered (m)50
Results explained
- Acceleration (m/s²)
- Acceleration (m/s²) from the formula above. Constant (average) acceleration only — if the acceleration varies, this is the mean over the interval. Velocities are signed: use negative values for motion in the opposite direction.
- Acceleration (ft/s²)
- Acceleration (ft/s²) from the formula above. Constant (average) acceleration only — if the acceleration varies, this is the mean over the interval. Velocities are signed: use negative values for motion in the opposite direction.
- Acceleration in g
- Acceleration in g from the formula above. Constant (average) acceleration only — if the acceleration varies, this is the mean over the interval. Velocities are signed: use negative values for motion in the opposite direction.
- Change in velocity (m/s)
- Change in velocity (m/s) from the formula above. Constant (average) acceleration only — if the acceleration varies, this is the mean over the interval. Velocities are signed: use negative values for motion in the opposite direction.
- Distance covered (m)
- Distance covered (m) from the formula above. Constant (average) acceleration only — if the acceleration varies, this is the mean over the interval. Velocities are signed: use negative values for motion in the opposite direction.

Every field is labelled with its unit — enter values in exactly the labelled unit and read the result in the labelled output unit. Fields with a unit symbol also support the site-wide imperial/metric switch, which converts before the formula runs.
It uses double-precision arithmetic and the published constants and formulas named on this page. The last displayed digit may be rounded, and real conditions can differ from the idealized model described in the assumptions.
