Estimate horsepower and torque, predict quarter-mile times, and optimize your vehicle's performance.
Convert torque measurements to horsepower at any RPM. Essential for dyno results and engine performance analysis.
Formula: HP = (Torque × RPM) / 5252
Calculate torque output from horsepower and RPM. Useful for comparing engine specifications and determining low-end power.
Formula: Torque = (HP × 5252) / RPM
Estimate your vehicle's quarter-mile elapsed time based on weight and horsepower. Great for predicting drag strip performance before modifications.
Note: Actual times vary significantly based on traction, driver skill, transmission type, and aerodynamics. This formula provides a baseline estimate.
These calculators help you measure, track, and optimize your vehicle's fuel economy and performance. Whether you're trying to save money at the pump or maximize acceleration, understanding these relationships is crucial.
When you change gear ratios or tire sizes, your speedometer and odometer no longer read correctly. A taller gear ratio (lower numerical value) or larger tires will make your odometer read fewer miles than you actually traveled, giving you an artificially high MPG reading. Our True MPG Calculator corrects for these modifications to show your real fuel economy.
Horsepower and torque are mathematically related but represent different aspects of engine performance. Torque measures the rotational force your engine produces, while horsepower measures how quickly that force can be applied. High torque at low RPM provides strong acceleration and towing capability, while high horsepower at high RPM enables high top speeds.
