Need to convert liter to gallon? Type the number of liters above, choose US or imperial gallons, and the answer appears as you type, with the same volume in quarts, pints and fluid ounces underneath. For US gallons you divide by 3.785411784 or, as a shortcut, multiply by 0.264172. Going the other way? Use the gallon to liter converter. Below you will find the formula, worked examples, a chart of 26 sizes, and the bottle, can and tank sizes people look up most.
One liter is 0.2641720524 US gallons, which rounds to 0.264172. In imperial gallons it is 0.2199692483, or about 0.219969. These are simply the reciprocals of 3.785411784 and 4.54609 liters per gallon. How many gallons per liter is that? Exactly the figures above, because gallons per liter is the small number and liters per gallon is the large one. A gallon count is therefore always roughly a quarter of the liter count. If you want fluid ounces instead of gallons, the liter to oz converter goes straight there.
US gallons = Liters ÷ 3.785411784
US gallons ≈ Liters × 0.264172
Imperial gallons = Liters ÷ 4.54609

Decimals use the same division: 1.5 liters is 0.3963 gallon, 2.5 liters is 0.6604, 3.5 liters is 0.9246, 4.5 liters is 1.1888 and 7.5 liters is 1.9813. Fractions such as 1/2 and mixed numbers such as 2 1/2 also work in the converter.
US gallons are often read as whole gallons plus quarts. Keep the whole gallons, then multiply the decimal part by 4. For 10 liters, 2.6417 gal is 2 gallons plus 0.6417 × 4, or 2.5669 quarts. For 20 liters, 5.2834 gal is 5 gallons plus 1.1338 quarts.
