CC to oz converter

What is a cc to oz converter?

A cc to oz converter is a tool that turns a volume written in cubic centimeters (cc, also written cm³) into fluid ounces (fl oz), and the other way around. Type a number on either side and read the converted value on the other. It is useful in cooking, automotive specifications, healthcare, and anywhere a metric volume needs to be expressed in the customary fluid-ounce scale used in the United States.

How are cubic centimeters and fluid ounces related?

A cubic centimeter is the volume of a cube measuring one centimeter on each edge, and it is identical to one milliliter. A US fluid ounce is a customary unit of liquid volume. The two are linked by a fixed factor:

$$1 \ \text{fl oz (US)} = 29.5735 \ \text{cc}$$

Equivalently, one cubic centimeter is a small fraction of a fluid ounce:

$$1 \ \text{cc} = \frac{1}{29.5735} \ \text{fl oz (US)} \approx 0.033814 \ \text{fl oz (US)}$$

Note that the UK (imperial) fluid ounce is slightly different, at about 28.4131 cc. This calculator lets you choose either definition.

How does the calculator work?

To go from cubic centimeters to US fluid ounces, divide by 29.5735:

$$V_{oz} = \frac{V_{cc}}{29.5735}$$

To go the other way, from US fluid ounces to cubic centimeters, multiply by the same factor:

$$V_{cc} = V_{oz} \times 29.5735$$

You can also switch either side to a related unit such as cubic millimeters, cubic meters, liters, milliliters, or the UK fluid ounce; the calculator then applies the appropriate factor automatically.

Worked examples

Example 1

You have 250 cc of liquid and want the figure in US fluid ounces. Dividing by the conversion factor:

$$\frac{250 \ \text{cc}}{29.5735} \approx 8.4535 \ \text{fl oz (US)}$$

Example 2

A recipe calls for 1 US fluid ounce and you want the equivalent in cubic centimeters:

$$1 \ \text{fl oz (US)} \times 29.5735 = 29.5735 \ \text{cc}$$

Practical notes

• The terms cc, cm³, and ml are fully interchangeable, so a cc to oz conversion is the same as an ml to oz conversion.
• US and UK fluid ounces differ: 1 US fl oz is about 29.5735 cc, while 1 UK (imperial) fl oz is about 28.4131 cc. Pick the right one for your context.
• A fluid ounce measures volume, not weight; do not confuse it with the avoirdupois ounce used for mass.
• Since 1 cc equals 1 ml, you can reuse the same factor with our cc to ml converter and ml to ounces converter.

Frequently asked questions

How many cc are in 1 fluid ounce?

A US fluid ounce contains about 29.5735 cc. A UK (imperial) fluid ounce contains about 28.4131 cc.

How do I convert cc to ounces?

Divide the number of cubic centimeters by 29.5735 to get US fluid ounces. For example, 100 cc divided by 29.5735 is about 3.3814 fl oz.

Is cc the same as ml for this conversion?

Yes. One cubic centimeter equals exactly one milliliter, so converting cc to fluid ounces gives the same result as converting ml to fluid ounces.

What is the difference between US and UK fluid ounces?

They are slightly different sizes. One US fluid ounce is about 29.5735 cc, while one UK (imperial) fluid ounce is about 28.4131 cc, making the UK ounce a little smaller.

Does this measure weight or volume?

A fluid ounce is a unit of volume. It is not the same as the ounce used for weight, so this converter should only be used for liquid volumes, not for masses.
