Convert cubic centimeters to horsepower calculator

Convert engine displacement (cubic centimeters) to estimated horsepower (hp) using engine displacement estimation formulas.

Input Parameters

Calculation Results

Estimated Horsepower (HP)

--

This is an estimated calculation based on engine displacement. Actual horsepower may vary based on other factors.

Calculation Formula

HP ≈ 0.133 * √(CC) / √(RPM/1000)

Where:
HP = Estimated Horsepower
CC = Engine Displacement in cubic centimeters
RPM = Engine Revolutions Per Minute

Learn how to use the Convert cubic centimeters to horsepower calculator calculator and its working principles

How to Use This Calculator

  1. Enter the engine displacement in cubic centimeters (CC). This is the primary parameter required for the calculation.
  2. Optionally, enter the engine's maximum RPM for a more accurate estimation. If left blank, the calculator uses a default RPM of 6000.
  3. Click the "Calculate" button to compute the estimated horsepower.
  4. The result will be displayed in horsepower (HP).

Understanding the Formula

The calculator uses the following formula to estimate horsepower based on engine displacement:

HP ≈ 0.133 * √(CC) / √(RPM/1000)

This formula provides a rough estimation of horsepower based on displacement and engine speed. It's based on the principle that larger displacement engines generally produce more power, and higher RPM allows for more power output within the same displacement.

Important Notes

  • This calculator provides an estimate and should not be considered precise. Actual horsepower depends on many factors including engine design, fuel efficiency, air-fuel ratio, and more.
  • The formula used is a simplified approximation and works best for small to mid-sized engines.
  • For accurate horsepower measurements, refer to engine specifications from the manufacturer.
