Acceleration Calculator
Acceleration in m/s² and in g, which is the legible one.
Work out Acceleration. Acceleration in m/s² and in g, which is the legible one. Answers in more than one unit, because SI is not always the legible one.
27.78 m/s is 100 km/h.
Standard gravity by definition. Local values run 9.78 to 9.83.
Acceleration (m/s²)
5.556
0.567 g
a = (v − u) ÷ t. Reporting it in g is what makes it legible: 5.56 m/s² means little on its own, while 0.57 g is directly comparable to the 1 g everything on Earth already experiences downward.
How the Acceleration Calculator works
a = (v − u) ÷ t. The result is given in g as well as m/s², because that is what makes it interpretable: 5.6 m/s² means little on its own, while 0.57 g is directly comparable to the gravity everything already experiences.

Frequently asked questions
How do I calculate acceleration?
Subtract the starting speed from the final speed and divide by the time. 0 to 27.78 m/s — that is 100 km/h — in 5 seconds gives 5.56 m/s².
What is g force?
Acceleration expressed in multiples of standard gravity, 9.80665 m/s². A 0.57 g launch is a quick car; sustained forces above about 5 g cause most people to lose consciousness.
What does negative acceleration mean?
Deceleration — the same arithmetic in the opposite direction. Braking from 20 m/s to a stop in 4 seconds is −5 m/s².
How far does it travel while accelerating?
s = ut + ½at², which this page shows. Under braking that figure is the stopping distance after the brakes are applied, not counting reaction time.
