Enter your engine displacement, engine speed, and engine efficiency into the calculator to determine your engine’s horsepower.

Horsepower Calculation Formula

The following formula is used to calculate the horsepower of an engine:

Horsepower = (Engine Displacement * Engine Speed * Engine Efficiency) / 5252

Variables:

  • Horsepower (HP) is the unit of measurement for engine power.
  • Engine Displacement is the total volume of all the cylinders in the engine (cc).
  • Engine Speed is the number of revolutions per minute (RPM).
  • Engine Efficiency is the percentage of the engine’s potential power output (%).

To calculate the horsepower, multiply the engine displacement by the engine speed and engine efficiency, then divide by 5252.

What is Horsepower Calculation?

Horsepower calculation refers to the process of determining the power output of an engine. This involves understanding various parameters like engine displacement, engine speed, and engine efficiency. Accurate horsepower calculation is crucial for engine tuning, performance analysis, and ensuring optimal engine operation.

How to Calculate Horsepower?

The following steps outline how to calculate the horsepower using the given formula:

  1. First, determine your engine displacement in cubic centimeters (cc).
  2. Next, determine the engine speed in revolutions per minute (RPM).
  3. Then, determine the engine efficiency percentage.
  4. Use the formula from above: Horsepower = (Engine Displacement * Engine Speed
