0-60 Acceleration Calculator

Physics

The 0-60 calculator works out the average acceleration of a vehicle that goes from a standstill to a chosen speed in a given time. Enter the 0-60 time (in seconds) and the speed reached (in mph) and you get the average acceleration in metres per second squared. It is handy for comparing the launch performance of cars or for physics homework on uniform acceleration.

Formula

Average acceleration = (Speed reached × 0.44704) ÷ Time, where speed is in mph and time in seconds (result in m/s²)
  • Average acceleration is the change in speed divided by the time taken: a = Δv ÷ t.
  • Because 1 mph equals 0.44704 m/s, the speed is converted to m/s before dividing by the time in seconds.
  • The result is an average over the whole run, not the peak acceleration, which is usually highest just off the line.
  • Dividing the acceleration by 9.80665 m/s² expresses it in g-force, the same units used for cornering and braking.
  • Real 0-60 times depend on traction, weather, surface, fuel load and driver, so two identical cars can post different figures.

Example Calculation

Inputs
  • 0-60 Time (seconds): 6
  • Speed Reached (mph): 60

A car reaches 60 mph from a standstill in 6 seconds. Converting 60 mph to 26.82 m/s and dividing by 6 seconds gives an average acceleration of about 4.47 m/s², or roughly 0.46 g.

Frequently asked questions

What does a 0-60 time actually measure?
It is the time, in seconds, a vehicle needs to accelerate from a complete standstill to 60 mph (about 97 km/h). It is a common benchmark for a car's straight-line acceleration.
Is this the average or peak acceleration?
This calculator returns the average acceleration over the whole run. Peak acceleration is higher, usually in the first moments off the line when grip and torque are greatest.
Why convert mph to m/s?
Acceleration in SI units is metres per second squared, so the speed has to be in metres per second first. One mph equals 0.44704 m/s.
What is a good 0-60 time?
Most everyday cars land between 7 and 10 seconds. Sports cars dip under 5 seconds, and high-end electric and supercars can beat 3 seconds.
How do I convert the result to g-force?
Divide the acceleration in m/s² by 9.80665. A car pulling 4.47 m/s² is accelerating at about 0.46 g.
