About US liquid gallon (gal)
The US liquid gallon is a unit of volume equal to 4 quarts, 8 pints, or 128 US fluid ounces, approximately 3.785 liters. It is the primary large liquid volume unit in the United States, used for fuel pricing at the pump, milk and juice packaging, and paint. US fuel economy is measured in miles per gallon (MPG). The US gallon is about 17% smaller than the UK imperial gallon (4.546 L), causing significant differences in fuel economy comparisons.
A gallon jug of milk is 3.785 L. Petrol (gasoline) is priced per US gallon at every US fuel station.
About Cubic mile (in³)
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.
US liquid gallon – Frequently Asked Questions
Why does the US still price fuel per gallon when the rest of the world uses liters?
US fuel infrastructure — pumps, tax law, pipeline contracts, and consumer expectations — is built around the gallon. Federal and state fuel taxes are levied per gallon; EPA fuel economy standards use miles per gallon; and consumers benchmark prices against a gallon reference ("$3 a gallon"). Switching to liters would require reprogramming every pump, rewriting tax code, and re-educating 330 million people who compare prices by the gallon. Canada made the switch in the 1970s during a broader metrication push, but the US never had the political will for a comprehensive changeover.
Why is the US gallon smaller than the UK gallon?
The US gallon (3.785 L) is based on the Queen Anne wine gallon of 1707 (231 cubic inches). The UK imperial gallon (4.546 L) was defined in 1824 as the volume of 10 pounds of water. The two systems diverged after US independence.
How does US MPG compare to L/100km?
To convert: L/100km = 235.2 ÷ MPG (US). A car achieving 30 MPG uses about 7.8 L/100km. UK MPG values are always higher than US MPG for the same car because the imperial gallon is larger.
How many gallons of water does a person drink per day?
Recommended daily water intake is about 2–3 liters (roughly 0.5–0.8 US gallons). The commonly cited "8 glasses a day" ≈ 64 fl oz ≈ 0.5 gallons ≈ 1.9 liters.
How many gallons does a car fuel tank hold?
Most US passenger cars have fuel tanks of 10–20 gallons (38–76 liters). Compact cars are typically 10–13 gallons; mid-size cars 14–17 gallons; SUVs and trucks 18–36 gallons.
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.
