About the milliliter and the US gallon
The milliliter
The milliliter (mL) is a metric unit of volume equal to one-thousandth of a liter, or one cubic centimeter. It is the everyday unit for medication dosing, beverage sizes outside the US, and cooking in most of the world. Note that a US fluid ounce is 29.5735 mL, while a UK fluid ounce is 28.4131 mL.
The US gallon
The US liquid gallon equals exactly 3.785411784 liters, defined as 231 cubic inches. It is the standard fuel and milk unit in the United States. The US gallon is about 16.7% smaller than the UK (imperial) gallon (4.54609 L), so quoting fuel economy as 'mpg' without specifying the gallon can mislead by a wide margin.
