so my hydromter reading is 39 g sugar /literhow dose this convert to specific gravety
Is that the only scale on the hydro?
that and % alcohol
To convert % alcohol, divide the number by .133 and then add the result to 1.xxx where the first x is 0if you only get a two-digit result from the division. For instance, the OG is 8%, divide by .133 to get 60.1, so the OG is ~1.060.
now that helps in calculating but that means my gravity went down by 0.012, should`t it go up?
During fermentation gravity will decrease as the yeast consume thesugar and converts it to alcohol.
