How to Use Beer Keg Weight to Take Beer Inventory

Here’s an example of how beer keg weight is used to determine the exact number of beers left in a keg. In terms of the type of kegs, let’s consider the very common half barrel keg, which we now know:

  • Is 160 pounds full
  • Is 30 pounds empty
  • Has 130 pounds of beer in it when full
  • Has 124 16-ounce pints in it when full

Knowing there are 124 16-ounce pints in a full half barrel, we know there are 1,984 fluid ounces* of beer in it.

*16-ounce pints are not in regular ounces but in fluid ounces, which is a measurement of volume, not weight. In the case of fluid ounces, 16 does not necessarily equal a pound of weight.

So, we have 1,984 fluid ounces in 130 pounds of beer. Let’s figure out how many fluid ounces per pound that is with this formula:

Total Fluid Ounces / Pounds of Beer = Fluid Ounces per Pound of Beer
1,984 fl. oz. / 130 lbs = 15.2 fl. oz. per pound

Each pound of beer weight in our keg corresponds to 15.2 fluid ounces.

If we weigh our half barrel keg and it’s 100 pounds, we know that 60 pounds of beer have been used. And 70 pounds of beer are left.

Knowing that each pound of beer is 15.2 fluid ounces we can calculate how many pints are left in the keg with this formula:

Pounds of Beer Left X 15.2 fl. oz. = Total fl. oz. Left in Keg
70 x 15.2 fl. oz.  = 1,064 fl. oz.

There is 1,064 fluid ounces of beer left in the keg. To find out how many pints that is, we divide by 16.

Total fl. oz. Left in Keg / 16 fl. oz. = Pints Left in Keg
1,064 fl. oz. / 16 fl. oz.  = 66.5

This keg of beer has 66 16-ounce pints left in it. Sorting out keg inventory can be one of the many bartender duties away from the bar.
