Brewing Calculators
Free brewing calculators in metric, US or imperial units, using the same formulas as Foambyte's brewing software.
ABV Calculator
Calculate the alcohol by volume (ABV) of your beer, cider or mead from its original and final gravity.
Keg Carbonation Calculator
Find the regulator pressure to force carbonate a keg to your target CO₂ volumes at any temperature, or check the carbonation your current pressure gives.
Priming Sugar Calculator
Calculate how much priming sugar to add when bottling beer, in total and per bottle, from the target carbonation, beer temperature and volume.
IBU Calculator
Calculate the bitterness (IBU) and alpha acid units of your hop additions with the Tinseth formula, in metric, US or imperial units.
Yeast Pitch Rate Calculator
Calculate how many billion yeast cells to pitch for your batch from the pitch rate, batch volume and wort gravity.
Yeast Viability Calculator
Estimate the viability of your yeast and the number of viable cells from its manufacture date, type and amount.
Gravity Converter
Convert wort and beer gravity between specific gravity, degrees Plato, degrees Brix, gravity points and degrees Oechsle.
Brewing Unit Converter
Convert brewing volumes, weights, temperatures and pressures between metric, US and UK units.
