Liters to Gallons Converter

This table covers common fuel and bulk-liquid measurements.

To convert liters to gallons, multiply the liter value by 0.2641720524. For example, 20 liters times 0.2641720524 equals approximately 5.28 gallons.

To go the other way, use the Gallons to Liters converter instead, which divides by the same factor for you. For the mid-size quart scale instead, see the Liters to Quarts converter below.

How Many Gallons in a Liter

A liter (also written litre or ltr) is about 0.264172 US gallon, so it takes about 3.785 liters to make one US gallon. Measured in UK imperial gallons, a liter is about 0.219969 imperial gallon.

This calculator uses the US gallon (3,785.411784 mL). The UK imperial gallon is a different, larger unit, about 4,546 mL, roughly 20% bigger. A fuel-economy or bulk-liquid figure quoted in UK gallons will not match this calculator's US-based ratio of about 0.264172 gallons per liter.

Where This Matters Most: Fuel Economy

Fuel economy figures are a common place this distinction causes confusion, since a US mile-per-gallon figure and a UK mile-per-gallon figure describe genuinely different-sized gallons, even before accounting for any real difference in fuel consumption.

To find what a volume weighs, the Liters to Pounds Converter converts liters to pounds for water, milk, flour, sugar, honey, or butter. The Gallons to Pounds Converter does the same starting from gallons. Since 1 liter is exactly 1,000 cubic centimeters, the Liters to Cubic Centimeters Converter covers volumes written in cc.
