THE PERFORMANCE TOOLBOX
Performance calculators
Put power, torque, acceleration and vehicle weight in context.
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.
Open calculator0–60 MPH
Calculate idealized time and distance to 60 MPH from an entered average acceleration. This kinematic worksheet does not infer acceleration from horsepower.
Open calculatorTorque to horsepower
Convert torque at a selected engine RPM into mechanical horsepower and kilowatts using power equals torque times angular speed.
Open calculatorWheel horsepower
Apply a user-selected percentage drivetrain loss to engine power. Compare the resulting wheel-power estimate without treating loss as a universal constant.
