History of Volume Measurement
The US gallon traces back to the English wine gallon of 231 cubic inches and is now standardized as exactly 3.785411784 liters. The liter is the metric unit of volume equal to one cubic decimeter. Because the imperial gallon (4.54609 L) is about 20% larger, US and UK fuel-economy and capacity figures are not directly comparable.
Quick Conversion Tips
For quick approximations, remember: 1 US gallon ≈ 3.8 L. To estimate liters from gallons, multiply by 4 and subtract a little: 5 gal × 4 = 20, actual is 18.93 L. For precise results, always use the exact factor of 3.785412.
