Calculate fluid ounces from cubic centimeters (cc), or cc from ounces, in one step. 1 cc equals 0.0338 US fluid ounces, plus imperial ounces, mL, and cups.
CC to Ounces Formula
A cubic centimeter (cc) is the same volume as a milliliter, so converting cc to fluid ounces is a single division. The factor depends on whether you want US or imperial (UK) fluid ounces.
fl oz (US) = cc / 29.5735
fl oz (Imperial) = cc / 28.4131
cc = fl oz * 29.5735 (US)
- cc: the volume in cubic centimeters, equal to milliliters.
- fl oz (US): the volume in US fluid ounces, where one US fluid ounce is 29.5735 cc.
- fl oz (Imperial): the volume in imperial fluid ounces, where one imperial fluid ounce is 28.4131 cc.
When you solve for ounces, the calculator divides your cc value by the cc-per-ounce factor for the ounce type you pick. When you solve for cc, it multiplies the ounce value by that same factor. The US fluid ounce is the default because it is the unit used on most labels and recipes in the United States. Choose the imperial ounce when you are working with UK measurements.
Common CC to Ounce Conversions
Use this table for quick reference. Values are rounded to two decimal places.
| Cubic centimeters (cc) | US fluid ounces | Imperial fluid ounces |
|---|---|---|
| 1 cc | 0.03 fl oz | 0.04 fl oz |
| 5 cc | 0.17 fl oz | 0.18 fl oz |
| 15 cc | 0.51 fl oz | 0.53 fl oz |
| 30 cc | 1.01 fl oz | 1.06 fl oz |
| 100 cc | 3.38 fl oz | 3.52 fl oz |
| 240 cc | 8.12 fl oz | 8.45 fl oz |
| 500 cc | 16.91 fl oz | 17.60 fl oz |
| 1000 cc | 33.81 fl oz | 35.20 fl oz |
The imperial fluid ounce is slightly smaller than the US fluid ounce, so the same cc volume gives a larger number of imperial ounces.
Example Problems
Example 1. You have a 250 cc serving and want it in US fluid ounces. Divide 250 by 29.5735. The result is 8.45 fl oz.
Example 2. A UK recipe calls for 4 imperial fluid ounces and you want the volume in cc. Multiply 4 by 28.4131. The result is 113.65 cc.
FAQ
Is a cc the same as a milliliter?
Yes. One cubic centimeter equals exactly one milliliter, so any cc value is also a milliliter value. This is why medical and cooking sources often use cc and mL interchangeably.
What is the difference between US and imperial fluid ounces?
A US fluid ounce is 29.5735 cc and an imperial (UK) fluid ounce is 28.4131 cc. The imperial ounce is about 4 percent smaller, so the same volume converts to a slightly higher number of imperial ounces. Pick the ounce type that matches the region of your recipe or label.
How do I convert cc to ounces by weight instead of volume?
This calculator converts volume to fluid ounces, which measure volume. To get weight ounces you also need the density of the substance. For water, 1 cc weighs about 0.0353 ounces, but other liquids differ, so a volume-to-weight conversion is not the same as a fluid ounce conversion.
