Estimate horsepower (HP) from engine displacement (CC), or convert HP to CC.
Related
The CC to HP calculator converts engine displacement (CC) into estimated horsepower (HP) and HP to CC. Choose your engine type for more accurate results, or leave the default “Rule of Thumb” option if you don't know your engine type.
CC (cubic centimeters) measures the total engine displacement, which is the total swept volume of the pistons inside the cylinders.
A higher CC generally indicates a larger engine that may produce more power, while a lower CC usually indicates a smaller engine. However, engine displacement is not the only factor that determines performance. Actual horsepower also depends on engine design, efficiency, and tuning.
There is no single exact formula to convert CC to horsepower, as engine design, efficiency, and tuning all play a role. However, for general estimation purposes, the standard rule of thumb is:
For a better result, use the formula that matches your engine type
HP = CC ÷ Engine Type Factor
To calculate engine displacement in CC from horsepower, rearrange the formula:
For a more accurate result, use the formula according to your engine type:
CC = HP × Engine Type Factor
For example, to convert 2,600 CC to horsepower for a 2-stroke engine, follow these steps:
The engine displacement is 2,600 CC.
For a 2-stroke engine, the conversion factor is 15 CC per HP.
HP = CC ÷ Engine Type Factor
HP = 2,600 ÷ 15
HP ≈ 173.33333
Note: This is an estimated conversion, and actual HP may vary depending on engine design, efficiency, RPM, tuning, and other factors.
You can verify this result instantly by entering the CC value into our CC to HP calculator.
Electric vehicles do not have a CC value
Higher CC engines generally produce more horsepower
HP also depends on engine efficiency, RPM, and design
The engine CC to HP calculator allows fast and accurate conversions from CC to HP and also works as an HP to CC calculator to estimate engine displacement (CC). Follow these steps to calculate the result:
There is no fixed conversion rate, as CC measures engine size/displacement, while HP measures power output of the Engine
The estimate depends on the type of engine:
The following chart shows the engine sizes and estimated horsepower using the standard 15 CC per HP formula:
| Engine Displacement (CC) | Estimated Horsepower (HP) | Common Use |
| 50 CC | 3.3 HP | Scooter, moped |
| 100 CC | 6.7 HP | Small motorcycle, scooter |
| 150 CC | 10 HP | Small motorcycle, go-kart |
| 250 CC | 16.7 HP | Motorcycle, dirt bike |
| 400 CC | 26.7 HP | Motorcycle, ATV |
| 500 CC | 33.3 HP | Mid-size motorcycle |
| 750 CC | 50 HP | Motorcycle, ATV |
| 1,000 CC | 66.7 HP | Motorcycle, passenger vehicle |
| 1,500 CC | 100 HP | Compact car, SUV |
| 2,000 CC | 133.3 HP | Sedan, SUV |
| 3,000 CC | 200 HP | Performance car, SUV |
Yes, the CC to Horsepower calculator provides the most accurate estimates for standard vehicles, motorcycles, and small utility engines.
Yes, this CC to HP converter works both ways. You can also use it as an HP to CC calculator to estimate engine displacement from horsepower.
A 1000cc (cubic centimeters) engine typically produces between 65- 200 HP. However, the HP conversion depends upon factors like engine type, tuning, and design.
Not necessarily; higher CC means larger displacement potential of the engine, but it does not always produce more horsepower. The horsepower depends heavily on engine tuning, engine efficiency, and RPM, etc.
Yes, you can increase horsepower without changing the CC of the engine. This is done by performance upgrades like exhaust modifications, turbocharging, and ECU tuning.
No. CC measures engine size, while horsepower measures power output. They are related but represent different physical properties.
Modern Formula 1 cars use a 1,600 CC (1.6-liter) turbocharged V6 internal combustion engine.
