0-60 mph Time Calculator

About this calculator

This calculator uses Patrick Hale's empirical formula, t = 5.825 × (weight/power)^(1/3), where weight is in pounds and power in horsepower — a cube-root power-to-weight relationship derived by fitting real-world 0-60 mph times across a wide range of production cars, rather than from first-principles physics.

Car enthusiasts, automotive journalists, and tuners use it as a quick sanity check on manufacturer-claimed acceleration figures or to estimate the effect of a weight-reduction or power upgrade before ever setting foot on a test track — it won't capture traction, gearing, or launch-control differences between vehicles, but it gets remarkably close for most stock cars.
