CC to HP Calculator

How to Use the CC to HP Calculator

This tool helps you estimate engine horsepower from CC, or convert horsepower back to CC. Results update instantly as you change values.

Step 1: Choose Conversion Type

Select CC → HP if you know the engine size. Select HP → CC if you know the horsepower and want to estimate engine capacity.

Step 2: Enter the Value

Enter the engine size in CC or the power in HP, based on the selected mode. You can use whole numbers or decimals.

Step 3: Select Engine Type

Choose the engine type that best matches your vehicle or machine.

• Standard: Regular car or motorcycle engines
• Small Engine: Generators, lawn mowers, tools
• Diesel: Diesel cars and machines
• Performance: Sport or high-output engines
• Turbo: Turbocharged or supercharged engines

Step 4: Choose Performance Level

Select how efficiently the engine performs. Higher levels assume better tuning and airflow.

What Results You Get

• Estimated Horsepower: Average expected HP
• Power Range: Realistic minimum and maximum HP
• Kilowatts (kW): Metric power equivalent
• Engine Size: Estimated CC (for HP → CC mode)

All results are estimates. Actual engine output may vary based on RPM, tuning, fuel quality, and mechanical condition.

FAQ

What is CC in an engine?
CC means cubic centimeters. It measures engine displacement, not power.

Can CC be directly converted to HP?
No exact formula exists. CC to HP is always an estimate based on engine efficiency.

Why do turbo engines make more HP?
Turbochargers force extra air into the engine, producing more power without increasing CC.

Is this calculator accurate?
This tool provides realistic ranges based on industry averages. Actual HP depends on RPM, tuning, fuel, and design.

Can I convert HP back to CC?
Yes. Use the HP → CC toggle to estimate required engine size.
