Follow the beer fermentation
A useful tool to correct the density of the wort when it is measured at a temperature different from one the hydrometer is set to.
Temperature adjustable in Celsius and Fahrenheit.
Density in SG, Plato and Baumé degrees.
It also allows the recording and the sharing of each reading over that the entire fermentation log.
Still, allows you to calculate the alcohol (ABV and ABW), both the real and the apparent attenuation.
It provides finally the freezing temperature of the wort and the caloric intake of the final beer.
