CC to HP Conversion Formula:
| From: | To: |
The CC to HP conversion is a simplified method to estimate engine horsepower from cubic centimeter displacement. While not exact due to various engine efficiency factors, it provides a rough approximation using the formula HP = CC / 15.
The calculator uses the conversion formula:
Where:
Explanation: This formula assumes an average engine efficiency where approximately 15 cubic centimeters of displacement produce 1 horsepower. Actual results may vary based on engine design, fuel type, and other factors.
Details: Understanding the relationship between engine displacement and horsepower helps in comparing engine performance, selecting appropriate engines for specific applications, and estimating power output for various mechanical systems.
Tips: Enter the engine displacement in cubic centimeters (cc). The value must be greater than zero. The calculator will provide an estimated horsepower output based on the standard conversion ratio.
Q1: How accurate is this conversion?
A: This is a rough approximation. Actual horsepower can vary significantly based on engine design, compression ratio, fuel system, and other efficiency factors.
Q2: Why divide by 15 specifically?
A: The divisor 15 represents an average efficiency factor. Some high-performance engines may have ratios closer to 10:1, while less efficient engines might be 20:1 or higher.
Q3: Can this formula be used for all engine types?
A: This formula works best for standard internal combustion engines. Electric motors, turbines, and other power sources require different calculation methods.
Q4: What are typical CC to HP ratios?
A: Modern engines typically range from 10-20 CC per HP. High-performance engines may be more efficient (lower ratio), while older or less efficient engines may have higher ratios.
Q5: Should this be used for precise engineering calculations?
A: No, this is an estimation tool. For precise calculations, consult manufacturer specifications or perform actual dynamometer testing.
