HP = CC / 15
| From: | To: |
The CC to HP conversion formula estimates horsepower from engine displacement in cubic centimeters for small engines. This simple formula provides a rough approximation of engine power output.
The calculator uses the formula:
Where:
Explanation: This formula divides the engine's cubic centimeter measurement by 15 to estimate horsepower. This is a general approximation and actual horsepower may vary based on engine design, efficiency, and other factors.
Details: Knowing the horsepower of small engines is important for selecting the right engine for applications like lawn mowers, generators, pumps, and other equipment. It helps ensure the engine has adequate power for the intended use.
Tips: Enter the engine displacement in cubic centimeters (cc). The value must be greater than zero. The calculator will provide an estimated horsepower value.
Q1: How accurate is this conversion?
A: This is a rough approximation. Actual horsepower can vary significantly based on engine design, efficiency, compression ratio, and other factors.
Q2: Does this work for all engine types?
A: This formula is most applicable to small 4-stroke engines. It may not be accurate for 2-stroke engines, diesel engines, or high-performance engines.
Q3: Why divide by 15 specifically?
A: The divisor of 15 is a general rule of thumb for small engines, representing the approximate ratio between displacement and horsepower for many standard designs.
Q4: Can I use this for automotive engines?
A: No, this formula is too simplistic for modern automotive engines which have much higher power outputs per cubic centimeter due to advanced technologies.
Q5: What's the typical HP range for small engines?
A: Small engines typically range from 1-25 HP, with common lawn mower engines in the 3-7 HP range and larger utility engines up to 25 HP.
