* A gallon: A gallon is equal to eight pints (US liquid pints). This is the closest equivalent if you're talking about volume.
* An eight-pack: If you're referring to a container of eight pints, like a package of beer, an eight-pack would be appropriate.
* Eight pints: Sometimes, the most straightforward answer is the best.
