We think a lot of the forced carbonation tables out there are great... but we believe in the K.I.S.S. principle, and knowing it could be improved we learned the formulas and made our own version. Hope you find it as handy as we do (and if you don't, tell us, and we'll fix it so that it is!)
 
This magnet measures 130mm by 90mm - small enough to be discreet when positioned near your regulator while still reading clearly. Looking for a .pdf version to download? Find it here.
