The liter is the metric unit of volume; the <strong>US liquid gallon</strong> is the US customary unit used at the fuel pump, on milk jugs and in recipes. The relationship is exact: <strong>1 US gallon equals 3.785411784 liters</strong>, so to convert liters to gallons you divide by 3.785411784, or multiply by 0.2641720524. For example, 10 L ÷ 3.785411784 = 2.6417 gallons. Watch the convention: a <strong>UK imperial gallon is about 4.546 liters</strong> — roughly 20% larger than a US gallon — so a figure converted with the wrong gallon is wrong by a fifth.
