Power to weight
Compare mechanical horsepower per US short ton, kilowatts per metric tonne and pounds per horsepower from vehicle power and race-ready weight.

Calculate idealized time and distance to 60 MPH from an entered average acceleration. This kinematic worksheet does not infer acceleration from horsepower.
Time follows the entered average acceleration. Distance additionally assumes the acceleration remains constant throughout the interval.
Not a horsepower-based prediction. An average acceleration alone cannot reconstruct a real variable-acceleration distance profile. No rollout, slope or shift modeling.
Follow the formula and keep the input units consistent at every step.
v = 60 × 0.44704 = 26.8224 m/s; a = entered g × 9.80665; time = v/a; distance = v²/(2a)At a constant 0.5 g, acceleration is 4.903325 m/s². Time to 60 MPH is about 5.47 s and distance about 73.36 m (240.68 ft).

Do not enter peak acceleration as an interval average.
Enter average longitudinal acceleration over the 0–60 interval. Do not enter peak acceleration as an interval average.
Displayed results are rounded for readability. Intermediate calculations retain floating-point precision; extra displayed decimals do not improve your input accuracy.
Yes. Select Metric above the calculator to convert your inputs. Results always state their units. Tire-size designations keep their conventional mm and inch units.

Constant-acceleration kinematics. Our 0–60 tool uses an entered average acceleration; it does not predict acceleration from horsepower.
