Convert cubic centimeters (cc) to fluid ounces and back. Supports US and imperial fl oz with instant cross-unit results for 10 volume units.
Converting between cubic centimeters and fluid ounces is one of the most common volume tasks in cooking, medicine, and science. One US fluid ounce equals 29.5735 cc (or mL), while an imperial fluid ounce equals 28.4131 cc. Knowledge of this relationship is essential when following recipes from different countries, measuring medication doses, or working with laboratory equipment.
Our CC to Oz Converter handles bidirectional conversion and lets you choose between US and imperial fluid ounces. It also provides parallel outputs in teaspoons, tablespoons, cups, pints, quarts, liters, and gallons so you never need a second tool. Scale bars offer a visual sense of how much liquid you are working with, and a collapsible reference table covers the most common container sizes.
Whether you are measuring cough syrup in cc and need the fluid-ounce label for dosing, converting a European beverage recipe, or comparing engine-oil capacities, this tool delivers precise results instantly.
Fluid-ounce conversions trip up nearly everyone because there are two different fluid ounces in use worldwide. This calculator removes ambiguity by letting you pick US or imperial ounces. By showing 10 output units at once, it eliminates the need to chain multiple converters and reduces the chance of rounding errors.
US: fl oz = cc ÷ 29.5735 | cc = fl oz × 29.5735 Imperial: fl oz = cc ÷ 28.4131 | cc = fl oz × 28.4131
Result: 3.3814 US fl oz
100 cc ÷ 29.5735 = 3.3814 US fluid ounces. This is roughly ⅓ of a cup or about 6.76 tablespoons.
A cubic centimeter (cc) is a metric unit equal to one milliliter (mL). It represents the volume of a cube measuring 1 cm on every side. Fluid ounces, by contrast, belong to the customary/imperial systems and are defined differently on each side of the Atlantic. The US fluid ounce is ¹⁄₁₂₈ of a US gallon (29.5735 mL), while the imperial fluid ounce is ¹⁄₁₆₀ of an imperial gallon (28.4131 mL). Knowing which system a recipe or label uses prevents costly measuring mistakes.
In healthcare, medications are often labeled in cc or mL but patient instructions may reference "ounces." A parent giving 5 mL of children's medicine needs to know that equals roughly ⅙ of a fluid ounce. In cooking, European recipes might specify 200 cc of cream, which an American cook needs to know is about 6.76 fl oz—just under ⅞ of a cup. Bartenders frequently convert cc to fl oz when using precision jiggers versus graduated cylinders.
Always confirm which fluid-ounce system a source is using before converting. For critical measurements (medications, lab reagents), use the exact factor rather than rounding. When precision below ±2 % is acceptable—such as in everyday cooking—the shorthand 30 cc ≈ 1 fl oz is perfectly safe and easy to remember.
One US fluid ounce equals exactly 29.5735 cc (mL). For quick estimates, 30 cc ≈ 1 fl oz.
Yes, by definition 1 cubic centimeter = 1 milliliter. They are completely interchangeable.
A US fluid ounce is 29.5735 mL, while an imperial (UK) fluid ounce is 28.4131 mL—about 4 % smaller.
One US cup is 236.588 cc (8 US fluid ounces). One metric cup is 250 cc.
Divide the cc value by 14.787. For example, 30 cc ÷ 14.787 ≈ 2.03 tablespoons.
The US fluid ounce descends from the US customary system while the imperial fluid ounce comes from the British imperial system defined in 1824. They diverged historically.
