Formula for 1 value: 1 US fl oz = 29.5735295625 cm³
Example: Convert 8 US fl oz to cm³. Multiply 8 by 29.5735295625, you get 236.5882365 cm³.
To convert by hand, you only need one step.
Take the number of US fluid ounces you have.
Multiply it by 29.5735295625.
The result is your volume in cubic centimeters.
Quick Answer
1 US fl oz = 29.5735295625 cm³
- 2 US fl oz = 59.147059125 cm³
- 8 US fl oz = 236.5882365 cm³
- 16 US fl oz = 473.176473 cm³
Conversion Formula
cm³ = US fl oz × 29.5735295625
This means cubic centimeters are bigger in number than fluid ounces. For every 1 US fluid ounce, you count 29.5735295625 cubic centimeters.
So you always multiply when going from US fl oz to cm³.
- Write down your value in US fl oz.
- Multiply it by 29.5735295625.

US fluid ounce
A US fluid ounce is a small unit of volume used in the United States for liquids. It is commonly used for drinks, recipes, and nutrition labels. See US fluid ounce.
It comes from the US customary system, which developed from older English measures. Today it is fixed as exactly 1/128 of a US gallon and is written as fl oz.
- Measuring water, milk, and juice servings
- Cooking and baking recipes in the US
- Beverage sizes like 8 fl oz or 12 fl oz
- Liquid medicine dosing cups and labels
- Cosmetics and personal care liquids
Cubic centimeter
A cubic centimeter is a metric unit of volume equal to the space of a cube that is 1 centimeter on each side. It is the same volume as 1 milliliter. See cubic centimeter.
It comes from the metric system, built on powers of 10 for easy scaling. Its symbol is cm³, and it is widely used in science, medicine, and engineering.
- Measuring small liquid volumes in labs
- Syringe and injection volumes (often shown as mL, same as cm³)
- Engine size in vehicles (for example, 125 cm³)
- Small container and package volume
- Science experiments and classroom measuring
Is this Conversion of US Ounce (fl oz) To Cubic Centimeter (cm³) Accurate?
Yes. This conversion is based on exact, standardized definitions. The US fluid ounce is defined from the US gallon, and the US gallon is defined as exactly 231 cubic inches. The inch is defined as exactly 2.54 centimeters, which makes the conversion to cubic centimeters precise and repeatable.
Our converter uses this standards based chain, so results match what you will see in textbooks and professional references. For the detailed standards we follow, read more at accuracy standards.
Real Life Examples
Here are practical examples showing where US fl oz to cm³ is useful in daily life and technical work.
- Cooking conversion: A recipe calls for 5 US fl oz of milk. That is 5 × 29.5735295625 = 147.8676478125 cm³, which is also 147.8676478125 mL.
- Water bottle label check: A drink is listed as 16 fl oz. That equals 473.176473 cm³, so it is about a 473 cm³ fill volume.
- Small medicine measure: You need 0.5 fl oz of cough syrup. That equals 14.78676478125 cm³, useful when a syringe is marked in mL or cm³.
- Coffee measurement: You pour 12 fl oz of cold brew into a jug. That is 354.88235475 cm³, helping when the jug scale is metric.
- Lab prep from a US note: A US instruction says add 2 fl oz of solution. In metric lab glassware, you measure 59.147059125 cm³.
- Cosmetic product refill: A face toner bottle holds 8 fl oz. In cm³, that is 236.5882365 cm³, helpful for comparing to a 250 cm³ container.
- Mixing a sports drink: You add 20 fl oz of water to a mix. That is 591.47059125 cm³, so a 600 cm³ shaker will be close to full.
Quick Tips
- To go from US fl oz to cm³, always multiply by 29.5735295625.
- For a fast estimate, use 30 cm³ per fl oz, then adjust down slightly.
- Remember that 1 cm³ equals 1 mL, so cm³ results can be read as mL.
- 8 fl oz is 236.5882365 cm³, useful for common drink sizes.
- 16 fl oz is 473.176473 cm³, close to a half liter.
- If you need high accuracy, keep the full factor 29.5735295625 in your calculation.
