Default help calculating gravity after boil

Hi all -

was unable to measure my OG after the boil today.

I did however have 13 gallons at 1.053 prior to the boil. I boiled off 2 gallons to end with 11 gallons

Is there a formula to calculate my OG after boil?

Thanks!

Beersmith 2's boil-off tool says your sitting at about 1.063...that's as long as you corrected your hydrometer back to 60 deg F for that first reading...

hope that helps!

53 * 13 / 11 = 63 or 1.063

-a.

(preboil gravity*preboil volume)=(postboil gravity*postboil volume)
