About the liter and the US gallon
The liter (litre) is 1,000 milliliters, or one cubic decimeter. It is the standard unit for drinks, fuel and fluid capacity almost everywhere outside the US, where gallons are still used at the pump.
The US liquid gallon divides into 4 quarts, 8 pints or 16 cups. It is the unit on US fuel pumps and for milk jugs; the UK imperial gallon is about 20% larger.
One US gallon equals 3.785412 liters, which makes the US gallon the larger unit of the two.
