What is the unit of capacity cc, and what is 1cc?
Cc is the abbreviation of the English name cubic centimeter. Under standard conditions, the capacity of 1ml water is very close to that of 1m3 (commonly known as cc), but it is not completely consistent. On the surface, cc and mL seem to be equivalent units, but strictly speaking, they are not. Cc is volume and mL is capacity, so be clear in your mind.
