How many 20 ounce beers can you get out of a full keg?

You can't determine the exact number of 20-ounce beers from a full keg without knowing the keg size. Here's why:

* Keg sizes vary: Kegs come in different sizes, the most common being:

* Pony keg: 1/2 barrel (15.5 gallons)

* Half barrel: 1/2 barrel (15.5 gallons)

* Full barrel: 1 barrel (31 gallons)

* Conversion factor: You need to convert gallons to ounces: 1 gallon = 128 ounces.

Here's how to calculate the number of beers:

1. Determine keg size: Find out the volume of your keg in gallons.

2. Convert to ounces: Multiply the keg size in gallons by 128 (ounces per gallon).

3. Divide by 20: Divide the total ounces by 20 (ounces per beer).

Example:

For a half barrel keg:

1. Keg size: 15.5 gallons

2. Total ounces: 15.5 gallons * 128 ounces/gallon = 1984 ounces

3. Number of 20-ounce beers: 1984 ounces / 20 ounces/beer = 99.2 beers

Note: You'll likely get slightly fewer than the calculated number due to some beer being lost in the tap and lines.
