How to Convert Gallons to Cases
Converting gallons to cases is essential for anyone purchasing beer in bulk, managing bar inventory, or planning large events. A standard beer case contains 24 bottles or cans of 12 ounces each, totaling 288 fluid ounces per case.
The Conversion Formula
The formula to convert gallons to cases is:
This formula works because one US gallon contains 128 fluid ounces, and a standard case contains 288 fluid ounces (24 beers x 12 oz each). Simplified, this gives us approximately 0.444 cases per gallon.
Example 1: Converting 15.5 Gallons to Cases
cases = 15.5 x 128 / 288 = 1984 / 288 = 6.89 cases
A half-barrel keg (15.5 gallons) equals about 7 cases of beer.
Example 2: Converting 31 Gallons to Cases
cases = 31 x 128 / 288 = 3968 / 288 = 13.78 cases
A full beer barrel equals about 14 cases of beer.
