During development of the carbonation calculators I noticed that there was some variation in the sources about a key constant: the mass of one liter of CO2 at standard temperature and pressure. The calculators were based upon the value of 1.969 from Kaminski (2019). Reddit user /u/chino_brews noted that this value was slightly off and suggested the following correction.
"One mole of CO2 has a mass of 44.01 g. AT STP, one liter [I think he meant mole] of gas occupies 22.4 L of volume. 44.01 / 22.4 = 1.96473214286."
The priming calculators have been updated with this new, more accurate constant. This small change probably doesn't make much difference at the homebrew level, but hey, why not? Increased precision is always valuable.

In other news, a FlexStyle calculator for ordinary bitter has been added. My interest in British styles was triggered by my homebrew store being sold out of Rahr two-row, so I went with Simpson pale ale malt instead. Brewing with British malt is new to me. I'm looking forward to it. I'm also currently interested in exploring session beers as part of a more healthy lifestyle.
