About Fluid Ounce to Cubic Centimeter Conversion

Converting fluid ounce to cubic centimeter comes up frequently in cooking, chemistry, medicine, and engineering. A recipe written in metric units may need to be adapted for a kitchen using cubic centimeter, or a laboratory protocol may specify volumes in fluid ounce that need to be measured with equipment calibrated in cubic centimeter.

In everyday use, knowing that 5 fl oz = 147.9 cm³ and 10 fl oz = 295.7 cm³ covers most common situations. For bulk calculations, 100 fl oz = 2957 cm³ is a useful anchor. The reverse conversion — cubic centimeter back to fluid ounce — uses the factor 0.03381, so 1 cm³ = 0.03381 fl oz.

All conversions use the internationally recognized factor of exactly 1 fl oz = 29.57 cm³. Calculations are performed in IEEE 754 double-precision floating point, giving accuracy to at least 8 significant figures — more than sufficient for any practical application.

Quick Answer

Formula: Cubic Centimeter = Fluid Ounce × 29.5735

Multiply any fluid ounce value by 29.5735 to get cubic centimeter. One fluid ounce equals 29.5735 cm³.

Reverse: Fluid Ounce = Cubic Centimeter × 0.033814057

Worked Examples

One fluid ounce
1 fl oz × 29.5735 = 29.5735 cm³
1 fl oz = 29.57 cm³.
Soda can
12 fl oz × 29.5735 = 354.882 cm³
12 fl oz = 354.9 cm³ = 1 standard can.
US cup
8 fl oz × 29.5735 = 236.588 cm³
8 fl oz = 236.6 cm³ = 1 US cup.
US pint
16 fl oz × 29.5735 = 473.176 cm³
16 fl oz = 473.2 cm³ = 1 pint.

Frequently Asked Questions

About Fluid Ounce and Cubic Centimeter

Fluid Ounce (fl oz)

The US fluid ounce is defined as 1/128 of a US gallon, exactly 29.5735 mL. The US and UK fl oz differ: the US is 29.57 mL while the Imperial fl oz is 28.41 mL.

Fluid ounces appear on every US beverage container: a soda can is 12 fl oz, a water bottle is 16.9 fl oz, and a US shot glass is 1.5 fl oz.

Interesting fact: Despite sharing the name 'ounce', the fluid ounce measures volume, not weight. One fl oz of water weighs about 1.04 oz, but one fl oz of honey weighs about 1.5 oz.

Cubic Centimeter (cm³)

The cubic centimeter (also cc or mL) is the volume of a cube measuring 1 cm on each side. It has been part of the CGS system since the 19th century, formalized by the British Association for the Advancement of Science in 1874.

In medicine and pharmacy, the cc is the preferred volume notation for injection doses, IV drips, and surgical implants. Automotive engineers use cc to express engine displacement.

Interesting fact: Because 1 mL = 1 cm³ exactly, the units are fully interchangeable — medical staff say 'cc' while chemists say 'mL'.
