The formula that works best only applies to the small newer normally aspirated (carbureted) 4 cycle engines. The ratios change slightly worse with altitude and slightly better with fuel injection and tuning. Most American mowers and the newer 4 cycle outboard motors fit into one of these two formulas: Typical new carbureted engine well tuned: 1 x HP per each 25 cc Fuel injected: 1 x HP per each 22 cc Notes:-Most engines are tuned down to a lower HP for better engine life. -It is common for the same cc engine to be built in 3 different HP versions with the highest rated being the maximized HP per cc version. That is how you see price and HP changes on the same cc engine made by the same company. -Some of the newest (2008 and newer) engines from Japan perform slightly better. A typical 150cc motor should equate to between 3.5 - 6 HP+ depending on tuning with 5 HP being the adv.
The actual formula plots as a curve and not linear but does not apply to Max/High Performance engines like motorcycles.

To convert cubic centimeters (cc) to horsepower (hp), a rough estimate is that 1 hp is approximately equal to 15 cc for small engines. Therefore, for a 40.9 cc engine, you can estimate that it produces about 2.73 hp (40.9 cc ÷ 15 cc/hp). However, this is a general approximation, and actual horsepower can vary based on engine design and efficiency.
To convert cubic centimeters (cc) to horsepower (hp), you can use a rough estimate where 1 hp is approximately equivalent to 15 cc in a typical gasoline engine. Therefore, 244 cc would be roughly equal to about 16.3 hp (244 cc ÷ 15 cc/hp). However, this is a general approximation and actual horsepower can vary based on engine design and efficiency.
To convert cubic centimeters (cc) to horsepower (hp), we typically use a general approximation that 1 hp is equivalent to around 15 cc for small engines. Therefore, for a 163 cc engine, it would be roughly estimated to produce around 10.9 hp (163 cc ÷ 15 cc/hp). However, actual hp can vary based on engine design and efficiency.
To convert horsepower (hp) to cubic centimeters (cc), you need to know the specific engine efficiency and type, as there isn't a direct conversion since they measure different things. However, a rough estimate often used is that 1 hp is roughly equivalent to about 15 cc in a gasoline engine. Therefore, to convert 40 hp to cc, you would multiply 40 by 15, resulting in approximately 600 cc. Keep in mind that this is a general approximation and actual values can vary based on the engine design.
you can't calculate the HP of a car by CC's. there's too many factors. you can always run it on a dynomo.
