About this calculator
Acceleration is the rate of change of velocity. The famous "0-60 mph in X seconds" is exactly this: Δv = 60 mph (≈ 26.82 m/s), divided by time. A sedan does 0-60 in ~8 s (3.4 m/s², 0.34 g). A sports car: 4 s (6.7 m/s², 0.68 g). A modern Tesla: under 2 s (>1 g).
Frequently asked
Why m/s²?+
It's the SI unit for acceleration. mph/s is more intuitive for cars; m/s² is universal in physics.
What is a "g"?+
g = 9.80665 m/s² — Earth's surface gravitational acceleration. 1g of acceleration feels like being pressed into the seat with a force equal to your weight.
What is 0-60 in 4 seconds?+
60 mph = 26.82 m/s. 26.82 / 4 = 6.7 m/s² ≈ 0.68 g. Fast — sports car territory.
Can acceleration be negative?+
Yes — that's deceleration (braking). Same formula, negative result.
Does this account for shifting time?+
No — it's the average acceleration across the whole interval. Real cars decelerate during shifts; the calculator gives the smoothed average.
