How the keg math works
First convert keg volume to US fluid ounces, then divide by your selected pour size. For guest planning, compute guests × drinks per guest and divide by pours per keg.
Real service volume can vary from foam, line length, and transfer loss, so ordering a small buffer is usually safer than ordering exact theoretical volume.
