I think Rick had the right answer.
Brix and Specific gravity are not a linear relationship so forget converting
back and forth
Brix is a measure of %sugar which Rick designated as "gravity units"
He adjusted the %sugar (68) by the change in volume(92/640) to get the new %
sugar (9.775) then converted to SG (1.039).

Subject: Re: confused about grape concentrate
How about this for a way to estimate your final gravity. To simplify the
calculations ignore the amount of liquid in the concentrate.
Multiply the brix measurement times 4. This gives 272 or a specific
gravity of 1.272. Multiply the 272 times 2 (2 cans of juice) you get 544
or a specific gravity of 1.544. Now dilute the juice with 5 gallons by
dividing by 5 to get 109 or a specific gravity of 1.109 which sounds about
right for the starting gravity of wine.
