About Cubic foot (ft³)
A cubic foot (ft³) is the volume of a cube with 1-foot sides, equal to approximately 28.317 liters or 7.48 US gallons. It is used in the United States for natural gas billing, refrigerator capacity, aquarium size, concrete orders, and shipping container dimensions. Refrigerators are rated in cubic feet of storage, natural gas consumption is billed in cubic feet, and HVAC airflow is measured in cubic feet per minute (CFM).
A full-size refrigerator is typically 18–28 ft³. Natural gas is billed in CCF (hundreds of cubic feet) in the US.
About US fluid ounce (us fl oz)
The US fluid ounce (fl oz) is a unit of volume equal to approximately 29.574 milliliters, one sixteenth of a US liquid pint. It is the primary small-volume unit on US food labels, beverage cans, and pharmaceutical liquid measurements. A standard US soda can is 12 fl oz; a coffee shop "tall" is 12 fl oz; a standard shot is 1.5 fl oz. The US fluid ounce is distinct from the imperial fluid ounce (28.413 mL) and should not be confused with the ounce as a unit of mass.
A US soda can is 12 fl oz (355 mL). A US shot glass holds 1.5 fl oz (44 mL). A US water bottle is commonly 16.9 fl oz (500 mL).
Cubic foot – Frequently Asked Questions
How many liters are in a cubic foot?
One cubic foot equals approximately 28.317 liters. Since 1 foot = 30.48 cm, 1 ft³ = 30.48³ cm³ = 28,316.8 cm³ = 28.317 liters.
Why is natural gas measured in cubic feet in the US?
The US gas industry adopted cubic feet before metrication became widespread. Natural gas is billed in CCF (hundred cubic feet) or therms (≈ 100 ft³ by energy content). Metric countries use cubic meters.
What does cubic feet mean for refrigerators?
Refrigerator capacity is rated in cubic feet of internal storage. A compact dorm fridge is 1–4 ft³; a standard family fridge is 18–22 ft³; a large French door model can exceed 28 ft³.
What is CFM (cubic feet per minute)?
CFM measures volumetric airflow rate. HVAC systems, range hoods, and fans are rated in CFM. A typical home range hood requires 100–600 CFM; a whole-home HVAC system might move 2,000 CFM.
How many US gallons are in a cubic foot?
One cubic foot equals approximately 7.48 US liquid gallons. This is commonly used in plumbing, aquarium sizing, and pool volume calculations.
US fluid ounce – Frequently Asked Questions
What is the difference between a fluid ounce and an ounce?
A fluid ounce (fl oz) is a unit of volume; an ounce (oz) is a unit of mass/weight. One US fluid ounce of water happens to weigh approximately 1.04 avoirdupois ounces — close but not equal. For other liquids, the mass per fl oz varies with density.
How many fluid ounces are in a US cup?
There are exactly 8 US fluid ounces in one US cup (240 mL). A pint is 16 fl oz, a quart is 32 fl oz, and a gallon is 128 fl oz.
What is the difference between US and imperial fluid ounces?
A US fluid ounce is approximately 29.574 mL; an imperial (UK) fluid ounce is approximately 28.413 mL — about 4% smaller. A US pint (16 fl oz) is 473 mL while a UK pint (20 fl oz) is 568 mL, a 20% difference that significantly affects beverage serving sizes.
How many fluid ounces are in a standard water bottle?
The most common US bottled water size is 16.9 fl oz (500 mL). Other sizes include 8 fl oz (237 mL), 20 fl oz (591 mL), and 33.8 fl oz (1 liter).
How many fl oz are in a standard US wine pour?
A standard US restaurant wine pour is 5 fl oz (148 mL). A 750 mL wine bottle yields approximately 5 pours of 5 fl oz each.
