Conversion Formula
The formula to convert cubic centimeters (cc) to horsepower (hp) is based on engine efficiency and standard estimations. It multiplies the cc value by a factor, typically around 0.013, which approximates the power output per cc. This works because engine power depends on how efficiently the engine converts fuel into mechanical energy. For example, 258 cc multiplied by 0.013 gives roughly 3.35 hp, showing how cc relates to power output in small engines or motorcycle engines.
Conversion Example
- Convert 150 cc to hp:
- 150 x 0.013 = 1.95 hp
- Convert 300 cc to hp:
- 300 x 0.013 = 3.9 hp
- Convert 400 cc to hp:
- 400 x 0.013 = 5.2 hp
- Convert 500 cc to hp:
- 500 x 0.013 = 6.5 hp
- Convert 100 cc to hp:
- 100 x 0.013 = 1.3 hp

Conversion Definitions
cc: Cubic centimeters (cc) measures the total volume of air/fuel mixture an engine’s cylinders can displace in one complete cycle, indicating engine size and capacity, impacting power output and performance.
hp: Horsepower (hp) is a unit of power measuring how much work an engine can perform over time, reflecting its ability to generate force and speed, especially in vehicles and machinery.
Conversion FAQs
How does engine efficiency affect the cc to hp conversion?
Engine efficiency greatly influences the cc to hp calculation because more efficient engines convert fuel into power more effectively. Higher efficiency engines produce more hp from the same cc, making the conversion an estimate rather than an exact measure.
Can I use this conversion for diesel engines?
This conversion works mainly for small gasoline engines, but for diesel engines, the power output per cc can differ due to combustion characteristics. Therefore, the standard factor of 0.013 might not be accurate for diesel engines, requiring specific adjustments.
What factors could cause variation in the cc to hp conversion?
Several factors like engine design, fuel type, compression ratio, and tuning influence the actual horsepower produced. The cc to hp formula provides an approximation, but real-world figures can vary depending on these engine specifics.
Is 258 cc a common engine size in motorcycles?
Yes, 258 cc engines are common in certain motorcycle models, providing a balance of power and fuel efficiency. The horsepower output for such engines generally ranges around 3 to 4 hp, depending on design and tuning.
