There are 1.5 pints in a fifth of whiskey.

A fifth is a common size for a bottle of liquor, and it can be bought or sold in many countries. A fifth contains 25 ounces, or 750 milliliters, of liquid. The liquid has no specific volume because it varies depending on the type of spirit and the proof (alcohol content) of the product.

In the United States, a fifth is legally defined as containing one-fifth (1/5) U.S. gallon or 3.785 liters of liquid at 40% alcohol by volume (ABV). This is equivalent to 375 milliliters at 80 proof strength, though most bottles will have different volumes based on their contents.

The origins of this term are unclear but some believe that it comes from the fact that five pints were equal to one gallon during medieval times in England when pints were measured at 473 milliliters instead of today’s 500 milliliter standard.
