Convert gallons to liters
liters = gallons × 3.7854
One gallon is 3.7854 liters, so multiply by 3.7854 to convert. Going the other way, one liter is 0.264172 gallons. These are US customary measures. An imperial (UK) gallon is 4.54609 L against the US gallon's 3.785411784 L, and the imperial pint, quart and fluid ounce differ too, so UK figures will not match.
