Horsepower Estimation Formula:
| From: | To: |
The CC to HP conversion is a rule of thumb used to estimate engine horsepower from engine displacement in cubic centimeters. This approximation provides a quick reference for comparing engine performance across different vehicles and applications.
The calculator uses the simple approximation formula:
Where:
Explanation: This formula assumes approximately 1 horsepower per 15 cubic centimeters of engine displacement, which is a general approximation that varies based on engine design, efficiency, and technology.
Details: Horsepower estimation helps in comparing engine performance, understanding vehicle capabilities, and making informed decisions when purchasing or modifying engines for various applications.
Tips: Enter engine displacement in cubic centimeters (cc). The value must be greater than 0. The result provides an approximate horsepower estimation based on the standard conversion ratio.
Q1: How accurate is this CC to HP conversion?
A: This is a rough approximation. Actual horsepower can vary significantly based on engine design, compression ratio, fuel system, and other factors.
Q2: Why divide by 15 specifically?
A: The division by 15 is a historical rule of thumb that provides a reasonable estimate for many conventional internal combustion engines.
Q3: Are there more accurate methods to calculate HP?
A: Yes, dynamometer testing provides precise horsepower measurements, and more complex formulas consider additional factors like torque and RPM.
Q4: Does this work for all engine types?
A: This approximation works best for conventional gasoline engines. Diesel engines, high-performance engines, and specialized motors may have different conversion ratios.
Q5: Can I use this for electric motors?
A: No, this formula is specifically for internal combustion engines measured by displacement. Electric motors use different performance metrics.
