What is the difference between injections of cc or ml?

Question

are the two the same of different? i have to take a b-12 shot and would like to know.

Answer 1

one cc is a cubic centimetre, so the same as one millilitre

Answer 2

they are equal.

Answer 3

Yep, they are exactly the same in reference-just different ways to measure it.

Answer 4

The concept of cc or cubic centimeter came before the milliliter.  The mL is the liquid amount in a cubic centimeter, a 3D measurement.
