🏎️ Engine Horsepower Calculator – Measure Engine Power Output

The Engine Horsepower Calculator helps you determine the power output of an engine based on torque, RPM, or other performance values. It is widely used in automotive engineering, racing, mechanics, and performance testing to compare engine efficiency and performance.

📘 What It Calculates:

  • ✅ Horsepower (HP) from torque and RPM using the formula:
    HP=(Torque×RPM)÷5252HP = (Torque × RPM) ÷ 5252HP=(Torque×RPM)÷5252

  • ✅ Brake horsepower (BHP), indicated horsepower (IHP), or shaft horsepower (SHP)

  • ✅ Helps compare performance across vehicles and engines

  • ✅ Useful for tuning, racing, and fuel efficiency studies

💡 Features:

  • Supports different units (lb-ft, Nm, RPM)

  • Calculates multiple horsepower types (gross, brake, shaft)

  • Useful for mechanics, engineers, and racers

  • Provides accurate insights into real-world performance

👤 Who Should Use This:

  • 📌 Automotive engineers & mechanics

  • 📌 Racers and car enthusiasts

  • 📌 Students learning mechanical/automotive engineering

  • 📌 Manufacturers testing engine performance

✅ Pro Tip:

Horsepower is a measure of how fast work can be done, while torque measures the twisting force that produces rotation. Both are important for performance analysis.

🔗 Related Tools:

Horsepower is a unit of power that measures the rate at which work is done, commonly used to describe engine output.

Using the formula HP = (Torque × RPM) ÷ 5252.

Torque is the rotational force, while horsepower measures how quickly that force can do work.

The horsepower measured at the engine’s output shaft without any power losses from accessories or drivetrain.
