HP / Torque / RPM Calculator
Enter any two values to calculate the third. Uses the formula: HP = (Torque x RPM) / 5252

HP vs Torque: What's the Difference?
Torque is the rotational force the engine produces. It determines how hard the engine can push. More torque = stronger acceleration at lower RPMs.
Horsepower is the rate at which work is done. It's torque multiplied by how fast the engine is spinning. More HP = higher top speed and sustained acceleration.
The 5252 RPM Crossover: HP and torque always cross at exactly 5252 RPM. Below 5252, torque is always higher than HP. Above 5252, HP is always higher. This is because HP = (Torque x RPM) / 5252, so when RPM = 5252, HP = Torque.
Simple rule: Torque wins races off the line. Horsepower wins races at the top end.
