Cubic centimeters to fluid ounces (cm³ to fl oz) converter

What is a cubic centimeters to fluid ounces converter?

A cubic centimeters to fluid ounces converter is an online tool that translates a volume given in cubic centimeters (cm³) into US fluid ounces (fl oz), and vice versa. The cubic centimeter is a metric unit equal to a cube one centimeter on each side, and it is identical to a milliliter (1 cm³ = 1 mL). The fluid ounce, on the other hand, belongs to the US customary system. Because these units come from two different measurement worlds, a converter is handy whenever you move between metric labels and US recipes, medical doses, or product specifications.

How it works

The conversion rests on a single fixed relationship: one US fluid ounce is defined as exactly 29.5735 cubic centimeters. To go from cubic centimeters to fluid ounces you divide by that factor; to go the other way you multiply by it. The converter performs this calculation in both directions automatically, so editing either field updates the other. Both fields also let you switch to related volume units such as quarts, gallons, and liters when you need a broader comparison.

Formula

To convert from cubic centimeters to US fluid ounces:

$\text{fl oz} = \frac{\text{cm}^3}{29.5735}$

To convert from US fluid ounces to cubic centimeters:

$\text{cm}^3 = \text{fl oz} \times 29.5735$

Conversion table

The table below lists common cubic centimeter values and their equivalents in US fluid ounces.

Examples

Example 1: 100 cm³ to fluid ounces

Divide the cubic centimeter value by 29.5735:

$\frac{100}{29.5735} \approx 3.3814 \text{ fl oz}$

So 100 cm³ is about 3.3814 US fluid ounces.

Example 2: 1 fluid ounce to cubic centimeters

Multiply the fluid ounce value by 29.5735:

$1 \times 29.5735 = 29.5735 \text{ cm}^3$

One US fluid ounce equals 29.5735 cubic centimeters.

Example 3: 2 fluid ounces to cubic centimeters

$2 \times 29.5735 \approx 59.147 \text{ cm}^3$

Two US fluid ounces come to roughly 59.147 cubic centimeters.

Example 4: 10000 cm³ to fluid ounces

$\frac{10000}{29.5735} \approx 338.14 \text{ fl oz}$

A volume of 10000 cm³ is about 338.14 US fluid ounces.

Notes

• This converter uses the US fluid ounce. The Imperial (UK) fluid ounce is slightly smaller, at about 28.4131 cm³, so results differ if you are working with UK measurements.
• A cubic centimeter and a milliliter are exactly the same volume, which makes this tool equally useful for converting milliliters to fluid ounces.
• Rounded results are shown for readability; the underlying calculation keeps full precision.

Frequently asked questions
