About Cubic Centimeters
A cubic centimeter (cm³), also written cc, is the volume of a cube with sides of one centimetre = exactly 1 mL. 'cc' is the preferred notation in medicine, mechanical engineering, and automotive contexts. Engine displacement is measured in cc (a 1,000 cc motorcycle engine has 1 L displacement); syringe dosages are labelled in cc. A standard sugar cube ≈1 cm³. 1 cm³ = 1 mL.
