Horsepower Formula:
| From: | To: |
The CC to HP conversion is a simplified formula that estimates engine horsepower from its displacement in cubic centimeters (CC). This approximation provides a quick reference for comparing engine power outputs.
The calculator uses the formula:
Where:
Explanation: This formula provides a rough estimate of horsepower based on engine displacement. Actual horsepower can vary significantly based on engine design, efficiency, and other factors.
Details: Engine displacement (CC) measures the total volume of all cylinders in an engine, while horsepower measures the engine's power output. The relationship between them is not linear and depends on many engineering factors.
Tips: Enter engine displacement in cubic centimeters (CC). The value must be greater than 0. This calculator provides an approximation and should not be used for precise engineering calculations.
Q1: How accurate is this conversion?
A: This is a rough approximation. Actual horsepower can vary by 20-30% or more depending on engine design, technology, and efficiency.
Q2: Why divide by 15 specifically?
A: The divisor 15 is a commonly used approximation for small to medium engines. Some formulas use different divisors (like 14-17) depending on engine type.
Q3: Does this work for all engine types?
A: This approximation works best for standard gasoline engines. Diesel engines, high-performance engines, and specialized engines may have different conversion ratios.
Q4: What factors affect the actual horsepower output?
A: Engine design, compression ratio, fuel system, turbocharging/supercharging, cooling efficiency, and many other factors affect actual horsepower.
Q5: Should I use this for vehicle purchasing decisions?
A: While this gives a rough idea, always refer to manufacturer specifications for accurate horsepower ratings when making important decisions.
