The volume fraction (percentage by volume, vol%) is one way of expressing the composition of a mixture with a dimensionless quantity; mass fraction (percentage by weight, wt%) and mole fraction (percentage by moles, mol%) are others.
Alcohol by volume (abbreviated as ABV, abv, or alc/vol) is a standard measure of how much alcohol is contained in a given volume of an alcoholic beverage (expressed as a volume percent).    It is defined as the number of millilitres (mL) of pure ethanol present in 100 ml (3.5 imp fl oz; 3.4 US fl oz) of solution at 20 °C (68 °F).

1 volume percent = 10,000 ppmv (i.e., parts per million by volume) with a million being defined as 10 6. Care must be taken with the concentrations expressed as ppbv to differentiate between the British billion which is 10 12 and the USA billion which is 10 9 (also referred to as the long scale and short scale billion, respectively).
Blood alcohol content (BAC), also called blood alcohol concentration or blood alcohol level, is a measurement of alcohol intoxication used for legal or medical purposes.
