how many beers is in a keg?

Indira Wassell: 3, 30 packs or so

Madge Voice: As a rough guide and using 12oz (350-355ml) as a standard beer, there are 165 beers in a 15.5 gallon keg.

Derick Kinnard: There is exactly 1984 ounces in a keg of beer. That is what we call a keg, which can actually come in many sizes, but the normal frat house keg (which is actually half a barrel) would have 165.3 - 12 oz beers, but most bar beers are 16 ounces (a pint) which would make it 124 - 16 oz beers.
