Understanding cc and mL
A cubic centimeter (cc or cm³) and a milliliter (mL) are the same volume. They are both equal to one-thousandth of a liter. The terms are used interchangeably in science, medicine, and engineering.
The Equivalence
Why Are They the Same?
By definition, 1 liter = 1,000 cm³ (1 cubic decimeter). Therefore:
- 1 liter = 1,000 cm³
- 1 milliliter = 1 liter ÷ 1,000 = 1 cm³
- So 1 mL = 1 cm³ = 1 cc
Where Is "cc" Used?
- Medicine — Syringes and IV bags are labeled in cc (e.g., "3 cc syringe").
- Automotive — Engine displacement measured in cc (e.g., "600 cc motorcycle").
- Science — Lab measurements for small volumes in experimental chemistry.
- 3D Printing — Material volume specifications in cc.
While both terms are correct, mL is the preferred SI unit in modern scientific publications. "cc" remains widely used in medical and automotive contexts.

Frequently Asked Questions
Common questions about cubic centimeters, milliliters, and their uses in medicine and engineering.
Yes, 1 cc is exactly equal to 1 mL. A cubic centimeter (cc or cm³) is the volume of a cube with 1 cm sides, which by definition equals 1 milliliter. The terms are completely interchangeable.
Historically, "cc" was the standard abbreviation in medical settings. Some hospitals now prefer "mL" to avoid confusion, since "cc" can be misread as "00" in handwritten prescriptions. The Joint Commission recommends using mL, but many practitioners still say "cc" verbally out of habit.
Engine "cc" refers to engine displacement — the total volume of all cylinders combined. A 600 cc motorcycle engine means its cylinders have a combined volume of 600 cubic centimeters (0.6 liters). Higher cc generally means more power and fuel consumption.
1 US teaspoon = approximately 4.929 cc (mL). This is commonly rounded to 5 cc (5 mL) for medical dosing. One tablespoon = ~15 cc (mL).
There is no difference. "cc" stands for cubic centimeter, which is the same as cm³. By SI definition, 1 cm³ = 1 mL exactly. The notation varies by field: "cc" in medicine, "cm³" in engineering and physics, "mL" in chemistry and food science.
There are exactly 1,000 cc in 1 liter. This is the same as 1,000 mL in 1 liter, or 1,000 cm³ in 1 cubic decimeter. To convert cc to liters, divide by 1,000.
Yes, absolutely. A 3 cc syringe and a 3 mL syringe are identical. Both hold exactly 3 cubic centimeters (3 milliliters) of liquid. The labeling difference is purely a matter of tradition or manufacturer preference.
