What is a Gallon (US) and a Cubic meter?
The US liquid gallon (symbol gal US) is a unit of volume in the United States customary units system. It is legally defined as 231 cubic inches, which is exactly equal to 3.785411784 liters. It is commonly used for measuring larger quantities of liquids, such as gasoline, milk, and paint.
The cubic meter (symbol m³) is the SI derived unit of volume. It is the volume of a cube with edges one meter in length. It represents a large volume and is often used for measuring capacities of containers, volumes of construction materials, or flow rates.
Note: The Gallon (US) is part of the imperial/US customary system, primarily used in the US, UK, and Canada for everyday measurements. The Cubic meter belongs to the metric (SI) system.
History of the Gallon (US) and Cubic meter
The gallon has ancient roots, evolving from various Roman and medieval units. The US liquid gallon is based on the wine gallon, which was standardized in England during the reign of Queen Anne in 1707 as 231 cubic inches. This definition was adopted by the United States. It differs from the Imperial gallon used in the UK and Canada.
The cubic meter is derived directly from the meter, the SI base unit of length, which has a history dating back to the French Revolution. As the standard unit of volume within the International System of Units (SI), established in 1960, the cubic meter is the foundation upon which other metric volume units (like the liter) are often related or defined (1 m³ = 1000 L).
Common Uses for US gallons and cubic meters
Explore the typical applications for both Gallon (US) (imperial/US) and Cubic meter (metric) to understand their common contexts.
Common Uses for US gallons
- US Fuel: Measuring fuel (gasoline, diesel) in the United States.
- US Beverages: Selling milk and other beverages in large containers in the US.

Frequently Asked Questions
Questions About Gallon (US) (gal)
Is a US gallon the same as an Imperial gallon?
No. The US gallon (≈ 3.785 L) is smaller than the Imperial gallon (≈ 4.546 L). Always specify which gallon is being used if there's ambiguity.
How many quarts are in a US gallon?
There are exactly 4 US liquid quarts in 1 US liquid gallon.
How many liters are in a US gallon?
1 US liquid gallon is exactly 3.785411784 liters.
About Cubic meter (m³)
How large is a cubic meter?
Imagine a cube that is 1 meter tall, 1 meter wide, and 1 meter deep. That volume is one cubic meter. It's equivalent to 1,000 liters or about 264 US gallons.
Is cubic meter the same as meter cubed?
Yes, these terms refer to the same unit, m³. 'Cubic meter' is the more common way to say it.
Why use cubic meters instead of liters?
The cubic meter is the official SI unit for volume, making it standard in many scientific and engineering fields requiring strict adherence to SI. It's also more practical for very large volumes where using liters would result in extremely large numbers.
