I updated the spreadsheets to let the user specify the headspace pressure, since the equilibrium pressure assumption would only be a ballpark estimate for keg filling under counter pressure and not applicable at all for bottle filling.

The spreadsheet lets you choose whether or not vessels are purged with CO2 before filling. If you choose the purged option, it assumes the headspace is 100% CO2 at the equilibrium pressure of the beer going into the vessel - which would need to be the case for successful counter-pressure filling...

Keep in mind that you need to carbonate both the beer and the headspace of any packaging container. So your beer volume and temperature matter, but so does your fill level in bottles/kegs/etc. I made a spreadsheet that takes those variables into account, which lives here...
