CC Unit Converter
Convert cc to mL, liters, cubic inches, and cubic feet.
Engine Displacement Calculator
Calculate total engine size (cc), liters, and cubic inches from bore, stroke, and cylinders.
If you need a fast and accurate cc calculator, you’re in the right place. This page includes two useful tools: a simple unit converter for cc and a full engine displacement calculator using bore, stroke, and cylinder count.
What does cc mean?
CC stands for cubic centimeters, a metric unit of volume. In everyday use, you’ll most often see cc used in two places:
- Engines (e.g., 125cc motorcycle, 1998cc car engine)
- Medical dosing (e.g., syringe volume; often interchangeable with mL)
Important: 1 cc = 1 mL. They represent the same volume.
How to use this cc calculator
1) CC unit conversion
Use the first calculator when you need quick conversions like:
- cc to mL
- cc to liters
- cc to cubic inches
- cubic inches to cc
Enter a value, choose your source and destination units, and click Convert.
2) Engine displacement (bore × stroke × cylinders)
Use the second calculator when building, tuning, or comparing engines. Enter bore and stroke in either millimeters or inches, add cylinder count, and click Calculate Engine CC.
CC formulas you should know
Basic volume conversions:
- 1 cc = 1 mL
- 1000 cc = 1 L
- 1 in³ = 16.387064 cc
- 1 ft³ = 28316.846592 cc
Engine displacement formula:
Volume per cylinder = (π / 4) × bore² × stroke
Total engine volume = volume per cylinder × number of cylinders
Practical examples
Example 1: Convert 500 cc to liters
500 ÷ 1000 = 0.5 L
Example 2: Convert 2.0 liters to cc
2.0 × 1000 = 2000 cc
Example 3: Estimate a 4-cylinder engine
If bore and stroke are both 86 mm with 4 cylinders, the result is about 1998 cc (roughly a 2.0L engine).
Why cc matters
- Vehicle comparison: Engine size can influence power, torque, fuel economy, and tax class in some regions.
- Medical accuracy: Correct cc/mL understanding helps prevent dosage confusion.
- Technical projects: Accurate volume conversion is essential in machining, fluid systems, and lab work.
Common mistakes to avoid
- Mixing up mm and inches in engine calculations
- Forgetting that 1 cc = 1 mL
- Rounding too early in multi-step calculations
- Using bore diameter incorrectly (formula expects full bore value, then squares it)
Quick FAQ
Is cc the same as horsepower?
No. CC measures displacement (volume). Horsepower measures power output. Larger cc can support more power, but tuning and design matter just as much.
Is 1000cc always 1 liter?
Yes. Exactly.
Can I use this for motorcycles and cars?
Yes. The same displacement formula applies to both, as long as your inputs are correct.
Final note
This calculator is designed for fast estimation and planning. For professional engine builds or regulated medical use, always verify numbers with official specs, manuals, and calibrated tools.
