Horsepower Calculation Formula:
From: | To: |
The CC to HP conversion is a general rule of thumb used to estimate engine horsepower from cubic centimeters displacement. While not precise for all engines, it provides a reasonable approximation for many small to medium-sized engines.
The calculator uses the simple conversion formula:
Where:
Explanation: This formula assumes approximately 15cc produces 1 horsepower, which is a common approximation for many internal combustion engines.
Details: Knowing the horsepower of an engine helps in understanding its performance capabilities, comparing different engines, and ensuring proper application for various mechanical and automotive uses.
Tips: Enter the engine displacement in cubic centimeters (cc). The value must be greater than 0. The calculator will provide an estimated horsepower value based on the standard conversion formula.
Q1: How accurate is this conversion?
A: This is a general approximation. Actual horsepower can vary significantly based on engine design, efficiency, compression ratio, and other factors.
Q2: Why divide by 15 specifically?
A: The 15:1 ratio is a common industry approximation that works reasonably well for many standard internal combustion engines.
Q3: Are there engines that don't follow this ratio?
A: Yes, high-performance engines may produce more horsepower per cc, while less efficient engines may produce less. Diesel engines typically have different power characteristics as well.
Q4: Can I use this for electric motors?
A: No, this formula is specifically for internal combustion engines. Electric motors use different power measurement standards.
Q5: What's the typical range for this conversion?
A: Most standard engines fall in the range of 10-20cc per horsepower, with 15:1 being a common average value.
