How many cc is 40 ml?

40 ml = 40 cc

Why is 40 ml exactly 40 cc?

Because the liter has been defined as exactly one cubic decimeter since 1964, which makes a milliliter one cubic centimeter. The factor is 1, so nothing is calculated: 40 ml = 40 cc. Between 1901 and 1964 the liter was 1.000028 dm³ and the two units differed in the fifth digit.

Is cc the same as cm³?

Yes, cc is only a keyboard-friendly spelling of cubic centimeter. 40 cc, 40 cm³ and 40 ml name one and the same volume, which is 0.04 L.

Where is cc used instead of ml?

In engine displacement — a 125 cc scooter — and on syringe barrels, where a 40 cc dose and a 40 ml dose are the same thing. Medication-safety guidance still asks prescribers to write ml, because a handwritten cc is easily misread as u for units.
