CC to Oz Converter — Cubic Centimetres to Fluid Ounces
Convert cc (cubic centimetres, identical to mL) to fluid ounces — choose US (29.574 mL/fl oz) or UK Imperial (28.413 mL/fl oz) — and see the equivalent in litres, cups, pints, quarts and gallons.
Input unit
Fluid-ounce standard
US: 1 fl oz = 29.574 mL
- 1
Volume (cc = mL)
100 - 2
fl oz = cc ÷ mL/oz
100 ÷ 29.5735 = 3.3814
How does this calculator work?
cc ÷ 29.574 = US fl oz; cc ÷ 28.413 = UK fl oz. Reverse: US fl oz × 29.574 = cc. Examples: 100 cc ≈ 3.381 US fl oz; 250 cc ≈ 8.45 US fl oz (≈ 1 US cup). cc and mL are identical units. Choose US or UK standard to match your product.
Formula
How this is calculated
A cubic centimetre (cc or cm³) equals one millilitre by SI definition, so cc-to-fluid-ounce and mL-to-fluid-ounce conversions are identical. The conversion factor depends on which fluid-ounce standard you are using — there are two in common use.
The US fluid ounce is defined as exactly 29.573 529 5625 mL (one US gallon = 231 cubic inches × (2.54 cm/in)³ ÷ 128). The UK / Imperial fluid ounce is defined as exactly 28.413 0625 mL (one Imperial gallon = 4.546 09 L ÷ 160). The US fl oz is therefore about 4% smaller than the UK fl oz. Always check which standard a recipe or specification uses — the difference matters for precise formulations.
For US cooking: 1 cup = 8 fl oz = 236.588 mL; 1 pint = 16 fl oz; 1 quart = 32 fl oz; 1 gallon = 128 fl oz. Imperial equivalents are proportionally different because the Imperial gallon is larger than the US gallon.
Frequently asked questions
A US fluid ounce equals 29.574 cc (= 29.574 mL). A UK Imperial fluid ounce equals 28.413 cc. Pick the standard that matches your recipe or product label.
The US fl oz is about 29.574 mL; the UK (Imperial) fl oz is about 28.413 mL — roughly 4% larger. The difference arises because the two systems define their gallons differently (US gallon = 3.785 L; Imperial gallon = 4.546 L). For cooking or medicine, always confirm which system your measurement uses.
Yes. 1 cc = 1 cm³ = 1 mL, exactly, by SI definition. The two unit names are used interchangeably — doctors often write mL, engineers write cc. Any cc-to-oz conversion is equally valid as an mL-to-oz conversion.
