Convert Cubic centimetres to US fluid ounces
1 cubic centimetre is 0.03 fl oz. One cubic centimetre is exactly 0.0338140227018 US fluid ounces.
One cubic centimetre is 0.033814023 US fluid ounces. To convert cubic centimetres to US fluid ounces, multiply by 0.033814023; to go the other way, divide by 0.033814023 or multiply by 29.57353. The relation is exact but the figure is not: it is a rounding of a number that does not terminate, and it follows from NIST Handbook 130. A thousandth of a litre, which makes it exactly a millilitre — the same volume under two names.

What is a cubic centimetre?
A thousandth of a litre, which makes it exactly a millilitre — the same volume under two names. Engine displacement uses cc and medicine uses ml for the identical quantity.
What is a US fluid ounce?
Exactly one 128th of a US gallon, which makes it 29.5735295625 ml exactly. The imperial fluid ounce is a different unit at exactly 28.4130625 ml, so a UK recipe calling for 10 fl oz means 284 ml and a US one means 296 ml. It is also a volume, not a weight: an ounce of flour is not a fluid ounce of flour.
How many US fluid ounces are in a cubic centimetre?
One cubic centimetre is 0.033814023 US fluid ounces. Going the other way, one US fluid ounce is 29.57353 cubic centimetres. Both figures come from the same defined relation rather than from a measurement, which is why they are the same today as they were in 1959.
