Formula
PSI = −16.6999 − 0.0101059T_F + 0.00116512T_F² + 0.173354T_FV + 4.24267V − 0.0684226V² (T_F = T_C × 9/5 + 32)Worked example. 3°C (37.4°F) targeting 2.4 volumes → about 9.9 PSI.
Method
Regression calibrated in °F, converted internally
This regression was fitted against Fahrenheit data, so this calculator converts your °C reading to °F internally before applying it. The regulator output stays in PSI, since that's how kegging hardware is graded everywhere, including in Canada.
Questions
CO2 is more soluble in cold liquid, so a colder keg absorbs the same number of volumes at a lower pressure than a warmer one would need.
Set-and-forget at serving pressure typically takes 1–2 weeks to fully equalize; agitating the keg or using a higher pressure briefly can shorten that to a day or two, but this calculator only gives the equilibrium PSI, not a timeline.
Kegging regulators and gauges are graded in PSI worldwide, including in Canada, so the output stays in PSI even though the temperature input is in °C.
