A fifth of whiskey contains 25.6 fluid ounces. The bottle contains onefifth of a gallon, and a gallon contains 128 fluid ounces; onefifth of 128 equals 25.6.
Several states had ordinances that set the measurement of 1/5 gallon as the legal threshold for selling liquor by the bottle or by the drink, which indicated whether the whiskey could be sold at a dry goods store or at a licensed barroom.
In the metric system, a fifth of whiskey contains 757.08 milliliters or roughly threequarters of a liter. This is roughly equivalent to the size of a standard wine bottle, which is 750 milliliters.
