Carbonation is set at the brewery and needs to be maintained through your entire draft system. This calculator uses the official Brewers Association equilibrium pressure table to give you the exact CO2 pressure required — plus elevation correction and system balance guidance.

BA Equilibrium Pressure Table — °F vs. Volumes CO2 (psig at sea level)
Source: Brewers Association Draught Beer Quality Manual, 4th Edition. Add 1 psi per 2,000 ft above sea level.
How to read this table: Find your keg temperature in the left column, then find your target volumes of CO2 across the top. The intersection is the PSI you need to set on your regulator. Highlighted cell = your current selection.
