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.

What Is CC in an Engine?

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.

CC to Horsepower Formula:

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:

HP = CC ÷ 15 (Rule of thumb)

For a better result, use the formula that matches your engine type

HP = CC ÷ Engine Type Factor 

HP to CC Formula:

To calculate engine displacement in CC from horsepower, rearrange the formula:

CC = HP x 15 (Rule of thumb)

For a more accurate result, use the formula according to your engine type:

CC = HP × Engine Type Factor 

How to Convert CC to Horsepower? 

For example, to convert 2,600 CC to horsepower for a 2-stroke engine, follow these steps:

Step #1: Find the Engine Displacement (CC)

The engine displacement is 2,600 CC.

Step #2: Determine the Engine Type Factor

For a 2-stroke engine, the conversion factor is 15 CC per HP.

Step #3: Apply the CC to HP Formula

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.

Facts to Know About CC and HP: 

  • Electric vehicles do not have a CC value

  • Higher CC engines generally produce more horsepower

  • HP also depends on engine efficiency, RPM, and design

How to Use the CC to HP Calculator? 

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:

  • Step 1: Choose CC to horsepower or horsepower to CC
  • Step 2: Enter the CC or HP value according to your choice in Step 1
  • Step 3: Choose the Engine Type from the drop-down menu
  • Step 4: Click the CALCULATE button to get the result along with step-by-step calculations

How much CC equals 1 HP?

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: 

  • Standard Passenger Cars & Commuter Bikes: Around 15 to 17 CC equals 1 HP (Formula: HP = CC ÷ 15)
  • Small Utility Engines: Around 30 to 35 CC equals 1 HP (Formula: HP = CC ÷ 35)
  • High-Performance Sportbikes & Racing Engines: Around 5 to 12 CC equals 1 HP, due to higher RPM 
  • Turbocharged or supercharged engines: In a turbo engine, a smaller CC can produce higher HP, so it sometimes exceeds 0.15–0.25 HP per CC

CC to HP Conversion Chart: 

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

FAQ's:

Can I use this calculator for all engine types? 

Yes, the CC to Horsepower calculator provides the most accurate estimates for standard vehicles, motorcycles, and small utility engines.

Can I convert HP back to CC? 

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.

How many horsepower is 1000 CC? 

A 1000cc (cubic centimeters) engine typically produces between 65- 200 HP. However, the HP conversion depends upon factors like engine type, tuning, and design.

Does higher CC mean higher horsepower? 

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.

Can you increase engine horsepower without changing the CC? 

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.

Are CC and HP the same?

No. CC measures engine size, while horsepower measures power output. They are related but represent different physical properties.

What is the CC of a Formula 1 car?

Modern Formula 1 cars use a 1,600 CC (1.6-liter) turbocharged V6 internal combustion engine.
