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 Cubic mile (mi³)
A cubic mile (mi³) is the volume of a cube with 1-mile sides, equal to approximately 4.168 trillion liters or about 4.168 km³. It is used in geoscience, hydrology, and environmental science to describe volumes of large water bodies, atmospheric water vapor, volcanic eruptions, and glacial ice. The total volume of Earth's oceans is approximately 320 million cubic miles. The unit is primarily used in US scientific and journalistic contexts.
The Great Lakes together contain about 5,440 mi³ of fresh water. The Amazon River discharges roughly 1.5 mi³ per day.
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.
Cubic mile – Frequently Asked Questions
How many liters are in a cubic mile?
One cubic mile equals approximately 4.168 × 10¹² liters (about 4.17 trillion liters) or roughly 4.168 km³. It is used only for planetary or geological scale volumes.
How much water is in the oceans in cubic miles?
Earth's oceans contain approximately 321 million cubic miles (1.335 billion km³) of water. The Pacific Ocean alone accounts for about 170 million cubic miles.
How does a cubic mile compare to a cubic kilometer?
One cubic mile equals approximately 4.168 cubic kilometers (km³). Geoscientists generally use km³; cubic miles appear mainly in US-origin journalism and older literature.
Is the cubic mile used in science?
The cubic mile is used in US-origin geoscience and hydrology texts for Great Lakes volumes, glacier mass loss, and ocean capacity. International scientific literature generally uses km³ instead.
How many cubic miles of water are in the Great Lakes?
The five Great Lakes together contain approximately 5,440 cubic miles (22,671 km³) of fresh water — about 21% of the world's surface fresh water. Lake Superior alone holds about 2,900 mi³.
