Horsepower Calculator

Calculate horsepower from torque and RPM, estimate power from quarter mile times, convert between HP and kW, and find power-to-weight ratios.

Calculate HP from Torque & RPM

Use the standard formula: HP = (Torque x RPM) / 5252

Torque

Engine RPM

RPM

Tip: Peak horsepower typically occurs at higher RPM than peak torque. Enter values from your dyno sheet or manufacturer specs for accurate results.

Note

These calculations provide estimates. Actual performance varies based on altitude, temperature, drivetrain losses, tire grip, and other factors.
