About Fluid Ounce to Cubic Foot Conversion

Converting fluid ounce to cubic foot 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 foot, or a laboratory protocol may specify volumes in fluid ounce that need to be measured with equipment calibrated in cubic foot.

In everyday use, knowing that 5 fl oz = 0.005222 ft³ and 10 fl oz = 0.01044 ft³ covers most common situations. For bulk calculations, 100 fl oz = 0.1044 ft³ is a useful anchor. The reverse conversion — cubic foot back to fluid ounce — uses the factor 957.5, so 1 ft³ = 957.5 fl oz.

All conversions use the internationally recognized factor of exactly 1 fl oz = 0.001044 ft³. 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

Multiply any fluid ounce value by 0.00104438 to get cubic foot. One fluid ounce equals 0.00104438 ft³.

Reverse: Fluid Ounce = Cubic Foot × 957.50588

Worked Examples

One cubic foot
957.5 fl oz × 0.00104438 = 0.99999386 ft³
957.5 fl oz = 1 ft³.
One fluid ounce
1 fl oz × 0.00104438 = 0.00104438 ft³
1 fl oz = 0.001044 ft³.
One US gallon
128 fl oz × 0.00104438 = 0.13368064 ft³
128 fl oz = 0.1337 ft³ = 1 gallon.
Soda can
12 fl oz × 0.00104438 = 0.01253256 ft³
12 fl oz = 0.01253 ft³.

Frequently Asked Questions

About Fluid Ounce and Cubic Foot

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 Foot (ft³)

The cubic foot is the Imperial and US customary volume unit equal to the space occupied by a cube with one-foot sides. It was formally standardized in the UK by the Weights and Measures Act of 1824.

Cubic feet appear in HVAC (airflow in CFM), natural gas billing in the US, and real-estate appraisals. One cubic foot equals exactly 1,728 cubic inches or approximately 28.317 liters.

Interesting fact: US natural gas meters read in CCF (hundreds of cubic feet) or MCF (thousands), making the cubic foot the invisible unit behind most American gas utility bills.
