1. 1
   Take your value in fluid ounces

   Start with the number of fluid ounces (fl oz) you want to convert.
2. 2
   Multiply by 0.001044

   The conversion factor from fl oz to ft³ is 0.001044. Multiply your value by this number.
3. 3
   Read the result in cubic feet

   The result is your value in cubic feet (ft³).

Multiply the value in fluid ounces by 0.001044. For the reverse direction, multiply by 957.50649.

• ✓1 US fl oz ≈ 29.6 ml; 1 UK fl oz ≈ 28.4 ml.
• ✓8 US fl oz ≈ 1 US cup ≈ 237 ml.
• ✓Use ml to avoid ambiguity between US and UK fluid ounces.

• ✗Mixing US and UK fluid ounces — 16 fl oz (US) = 473 ml vs. 16 fl oz (UK) = 455 ml.
• ✗Confusing fluid ounce (volume) with avoirdupois ounce (mass).
• ✗Assuming 1 fl oz = 1 oz by weight — only true for pure water and approximately.

What is the Fluid Ounce?

The US fluid ounce equals exactly 29.5735295625 milliliters and is the standard small-volume unit for beverages, cocktails, personal-care products, and cooking in the United States. It is distinct from the (weight) ounce: 1 fluid ounce of water weighs about 1 ounce by weight at room temperature, but other liquids may weigh more or less. Soft-drink cans (12 fl oz), beer bottles (12 fl oz), shampoo bottles, and skin-cream tubs all label volume in fluid ounces. The US fluid ounce is slightly different from the UK imperial fluid ounce (28.4131 mL — about 4% smaller), reflecting the different gallon definitions. The US fl oz relates to the gallon (128 fl oz = 1 gal), the cup (8 fl oz = 1 cup), the tablespoon (2 tbsp = 1 fl oz), and the milliliter (1 fl oz ≈ 29.57 mL). Cocktail recipes universally use fluid ounces.

What is the Cubic Foot?

The cubic foot equals approximately 28.317 liters (or exactly 1,728 cubic inches) and is the American standard volume unit for HVAC capacity, natural-gas billing, refrigerator interior volume, and bulk material like concrete or mulch. American gas utilities measure delivered gas in 'CCF' (hundred cubic feet) or 'MCF' (thousand cubic feet), even when the customer thinks in terms of monthly bills. Refrigerators are advertised by their interior cubic-foot capacity (typical home unit: 18–25 ft³). Air-conditioning systems are rated in CFM (cubic feet per minute) airflow. Concrete is sometimes priced by the cubic yard (27 ft³), and mulch and topsoil are often sold by cubic foot bags. The cubic foot relates to the cubic yard (27 ft³ = 1 yd³), the cubic inch (1,728 in³ = 1 ft³), the cubic meter (1 ft³ ≈ 0.0283 m³), and the gallon (1 ft³ ≈ 7.481 US gal).
