When you pick up a bottle of whisky, one of the most prominent numbers on the label—aside from the age statement—is the Alcohol by Volume (ABV).

Historically, the British Royal Navy tested rum (and later whisky) by mixing it with gunpowder. If the gunpowder still ignited, the spirit was "proof" (meaning it had enough alcohol to burn). That threshold was roughly 57% ABV (4/7ths alcohol by volume). Today, a few distilleries release "Navy Strength" expressions as a nod to history.
