About Cubic Centimeter to Fluid Ounce Conversion

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

In everyday use, knowing that 5 cm³ = 0.1691 fl oz and 10 cm³ = 0.3381 fl oz covers most common situations. For bulk calculations, 100 cm³ = 3.381 fl oz is a useful anchor. The reverse conversion — fluid ounce back to cubic centimeter — uses the factor 29.57, so 1 fl oz = 29.57 cm³.

All conversions use the internationally recognized factor of exactly 1 cm³ = 0.03381 fl oz. 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: Fluid Ounce = Cubic Centimeter × 0.033814057

Multiply any cubic centimeter value by 0.033814057 to get fluid ounce. One cubic centimeter equals 0.033814057 fl oz.

Reverse: Cubic Centimeter = Fluid Ounce × 29.5735

Worked Examples

One fluid ounce
29.57 cm³ × 0.033814057 = 0.99988165 fl oz
29.57 cm³ = 1 fl oz.
Soda can
355 cm³ × 0.033814057 = 12.00399 fl oz
355 cm³ = 12 fl oz = 1 standard can.
US pint
473 cm³ × 0.033814057 = 15.994049 fl oz
473 cm³ = 16 fl oz = 1 US pint.
US cup
236.6 cm³ × 0.033814057 = 8.0004058 fl oz
236.6 cm³ = 8 fl oz = 1 US cup.

Frequently Asked Questions

About Cubic Centimeter and Fluid Ounce

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'.

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.
