HP to CC Formula:
| From: | To: |
The HP vs CC calculation provides an approximate relationship between engine horsepower (HP) and engine displacement in cubic centimeters (CC). This ratio helps in understanding engine performance characteristics and comparing different engines.
The calculator uses the simplified formula:
Where:
Explanation: This formula provides a rough estimate based on the general relationship between engine displacement and power output. Actual horsepower can vary based on engine design, technology, and other factors.
Details: Understanding the HP to CC ratio helps in evaluating engine efficiency, comparing performance across different engine sizes, and making informed decisions when purchasing vehicles or engines.
Tips: Enter the engine displacement in cubic centimeters (CC). The calculator will provide an estimated horsepower value. Remember this is an approximation and actual horsepower may vary.
Q1: How accurate is the CC to HP conversion?
A: This is a rough estimate. Actual horsepower depends on many factors including engine design, compression ratio, fuel system, and technology.
Q2: Why is the ratio approximately 1:15?
A: This ratio represents a general average across many engine types, but modern engines often have better power-to-displacement ratios.
Q3: Can two engines with same CC have different HP?
A: Yes, significantly. Engine technology, turbocharging, fuel injection systems, and design efficiency can cause large variations in horsepower.
Q4: What is a good HP to CC ratio?
A: Higher ratios indicate more efficient engines. Modern performance engines often exceed 1 HP per 10 CC, while older engines may be closer to 1 HP per 20 CC.
Q5: Does this apply to all engine types?
A: This is most applicable to internal combustion engines. Electric motors and other power sources use different measurement systems.
