L to Gal Converter – Convert liters to US gallons

This converter applies the exact factor 1 liter = 0.26417205 US gallons. Multiply any value in liters by 0.26417205 to get US gallons: the worked example 10 L × 0.26417205 = 2.64 gal shows the arithmetic in a single line. Liters and milliliters rule the metric kitchen and fuel pump, while US gallons, cups and fluid ounces fill American recipes, gas stations and bottle labels — and the imperial gallon used in the UK is a third system again. Every US liquid unit in this converter derives from the exact gallon of 3.785411784 L, so results are definition-exact: 1 fl oz = 29.5735295625 mL and 1 cup = 236.5882365 mL. For reverse conversions divide by 0.26417205 instead — identical to multiplying by 3.7854118 — for example 2.64 gal ≈ 9.99 L. Quick mini table: 1 L = 0.264172 gal; 5 L = 1.32 gal; 10 L = 2.64 gal; 50 L = 13.21 gal; 100 L = 26.42 gal. Spot-check with fuel: a 15 US-gallon tank is about 56.8 L, and a 500 mL bottle is 16.9 fl oz — two anchors that expose a US/UK gallon mix-up immediately.
