CC Calculation Formula:
From: | To: |
The HP to CC conversion provides an approximate calculation of engine displacement (cubic centimeters) from horsepower. This conversion uses a general rule of thumb where 1 horsepower is approximately equal to 15 cubic centimeters.
The calculator uses the simple conversion formula:
Where:
Explanation: This formula provides a rough estimate of engine displacement based on horsepower output, though actual values may vary depending on engine efficiency and design.
Details: Understanding the relationship between horsepower and engine displacement helps in comparing engine performance, estimating engine size requirements, and making general comparisons between different engine types.
Tips: Enter the horsepower value you want to convert. The calculator will provide the approximate cubic centimeter equivalent using the standard conversion factor of 15cc per horsepower.
Q1: How accurate is this conversion?
A: This is a rough approximation. Actual CC per HP can vary from 10-20 depending on engine efficiency, type, and technology.
Q2: Why is there a range in the conversion factor?
A: Different engine designs (2-stroke vs 4-stroke, diesel vs gasoline, naturally aspirated vs turbocharged) have different power densities and efficiencies.
Q3: Can I use this for all engine types?
A: This conversion works best for general comparisons of small to medium internal combustion engines. High-performance or specialty engines may have different ratios.
Q4: Is this conversion linear?
A: Yes, the conversion uses a simple linear relationship where CC increases proportionally with horsepower.
Q5: What are typical CC values for common horsepower ratings?
A: For example: 5hp ≈ 75cc, 10hp ≈ 150cc, 20hp ≈ 300cc, 50hp ≈ 750cc, though actual values may vary.
