🚗 Horsepower Calculator – Measure Engine Power & Performance

The Horsepower Calculator helps determine the power output of an engine based on torque, speed, or other performance factors. It is widely used in automotive engineering, racing, mechanics, and industrial applications to evaluate how much work an engine can perform.

📘 What It Calculates:

  • ✅ Horsepower (HP) using torque and RPM formula

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

  • ✅ Conversion between horsepower, kilowatts, and watts

  • ✅ Power-to-weight ratio for vehicles

💡 Features:

  • Input torque and RPM to calculate horsepower

  • Supports metric and imperial units

  • Useful for cars, motorcycles, boats, and machinery

  • Helps compare vehicle performance and efficiency

👤 Who Should Use This:

  • 📌 Automotive engineers testing engines

  • 📌 Mechanics tuning vehicles

  • 📌 Racers measuring car/bike performance

  • 📌 Students learning physics and mechanics

✅ Pro Tip:

Horsepower is directly related to torque and engine speed – higher RPM with strong torque = higher horsepower.

🔗 Related Tools:

Horsepower (HP) is a unit of power that measures how much work an engine can perform over time.

James Watt introduced it to compare steam engines to horse labor.

HP = (Torque × RPM) ÷ 5252 (in imperial units).

The actual engine output measured at the crankshaft, without losses from gears or accessories.
