The US gallon is a unit of volume equal to 128 US fluid ounces, or approximately 3.785 liters, used for large liquid volumes.
1 US gal = 4 US qt = 8 US pt = 16 US cups = 128 US fl oz = 3.785411784 L.
To liters: multiply by 3.785. To UK gallons: multiply by 0.832674. To cubic meters: multiply by 0.003785.
Fuel prices ($/gal), milk jugs, water cooler bottles, swimming pool chemicals, and paint quantities.
The US gallon is smaller than the UK gallon: 3.785 L vs. 4.546 L. This means UK fuel economy figures look better by number!
Confusing US and UK gallons — UK gallons are 20% larger. Fuel economy (mpg) differs significantly between the two systems.
1 gallon ≈ 3.8 liters ≈ a large milk jug. 4 quarts = 1 gallon. A gallon of water weighs about 8.3 pounds.
The exaliter is a unit of volume equal to 10¹⁸ liters, or one million cubic kilometers.
1 EL = 10¹⁸ L = 10¹⁵ m³ = 10⁶ km³ = 1,000 PL.
To liters: multiply by 10¹⁸. To km³: multiply by 10⁶. To petaliters: multiply by 1,000.
No practical applications — this scale exists only for astronomical and theoretical comparisons.
All the water on Earth (oceans, ice, groundwater, lakes, rivers, atmosphere) totals about 1.386 EL.
Almost never encountered, so mistakes are rare. The main risk is confusion with other 'E' prefixes (e.g., eV in energy).
Think of the exaliter as the 'planet volume' unit. Earth's oceans ≈ 1.335 EL. Prefix: exa = 10¹⁸ = quintillion.
