Horsepower Calculator
Calculate horsepower based on quarter-mile stats or estimate performance based on your vehicle’s power
About Horsepower Calculation
Horsepower is a unit of measurement for power, commonly used to quantify the power output of engines and motors.
These calculations use established formulas to estimate horsepower based on quarter-mile performance metrics:
HP = (Weight / (ET / 5.825))³
HP = (Trap Speed / 234)³ × Weight
ET = 5.825 × (Weight / HP)^(1/3)
Note: Results are estimates. Actual performance may vary based on traction, weather conditions, and other factors.
