HP = CC / 15 Formula:
| From: | To: |
The CC to HP conversion is a simplified formula used to approximate horsepower from engine displacement in cubic centimeters. This formula (HP = CC / 15) provides a rough estimate for small engines and is commonly used in automotive and small engine applications.
The calculator uses the simple conversion formula:
Where:
Explanation: This formula provides a general approximation where 15 cubic centimeters of displacement roughly equals 1 horsepower for small engines.
Details: Knowing the horsepower of an engine helps in understanding its power output, comparing engine performance, and ensuring proper application for specific tasks and equipment.
Tips: Enter the engine displacement in cubic centimeters (cc). The value must be greater than 0. The calculator will provide the estimated horsepower.
Q1: How accurate is the CC to HP conversion?
A: This is a rough approximation. Actual horsepower can vary based on engine design, efficiency, compression ratio, and other factors.
Q2: Does this formula work for all engine types?
A: This formula is most accurate for small 4-stroke engines. Different engine types (2-stroke, diesel, high-performance) may have different conversion ratios.
Q3: Why divide by 15 specifically?
A: The division by 15 is based on average efficiency of small engines. Some formulas use different divisors (10-17) depending on engine technology and era.
Q4: Can I use this for automotive engines?
A: While the basic principle applies, modern automotive engines are more efficient and may produce more horsepower per cubic centimeter than this formula suggests.
Q5: What's the difference between CC and HP?
A: CC (cubic centimeters) measures engine displacement (size), while HP (horsepower) measures power output. Larger displacement generally means more potential power.
