What does c.c. stand for in volume measurements?

• A. Cubic centimeter
• B. Celsius centiliter
• C. Cup centi
• D. Cubic centimeter (alt)

Answer: (A)

Ccc stands for a unit of volume in the metric system: cubic centimeter. One cubic centimeter equals one milliliter, so c.c. and mL describe the same amount of liquid. This is why c.c. is common in medical dosing and syringe measurements for small volumes. The other options aren’t standard terms for this abbreviation—Celsius centiliter isn’t a recognized unit, cup centi isn’t a metric term, and the alternate phrasing repeats the same idea in an odd form. In practice, you’ll see c.c. used interchangeably with mL, but the fundamental idea is that a cubic centimeter is a milliliter in volume.
