I know brewing sw does it, but how would you calculate/correct the gravity of 4.5 gals to 5 gals ?
If I have 4.5 gals @ 1060, then what is gravity @ 5 gals (same temp)
I figure that .5 gallons represents 1/9 increase in volume ... does that mean gravity goes down by 1/9 ? Is the rel strictly linear ?
If that were true, then a 100% increase in volume should give a 100% decrease in gravity ? (Obviously 9 gals would still be thicker than water, so the math is a little fuzzy)
I am just trying to determine the corrected gravity if my final volume were the correct amount of 5 gals...
