ABOUT THIS CONVERSION
Convert liters to US gallons
Liters are metric volume units, while the US liquid gallon is used for fuel and containers in the United States. One US liquid gallon is exactly 3.785411784 liters; this is not the larger Imperial gallon.
Real-world example
A 2 L container holds 0.5283441 US gal. Product labels may round both quantities independently, so package markings are not always exact reverse conversions.
Rounding and precision
For packaging, round to the labeled container precision. Laboratory and dosing work must follow calibrated equipment and required tolerances. Keep full precision during the conversion and round only after the final unit is chosen.
Regional context
A US liquid gallon is not an Imperial gallon, and their fluid ounces differ. Every customary entry here is labeled as US where ambiguity matters; the plain fluid-ounce entry uses the US liquid definition.
Common mistake
Check the word ‘US’ before using a gallon result. One Imperial gallon is 4.54609 liters and would produce a materially different answer.
Editorial method
Definitions and sources are listed below. Calculations retain more precision than the default display and round only for presentation.
