1 lb of sugar = 454 grams = 46 gravity points.

330 grams of sugar = 33 gravity points

Your OG was 1.062 (I think that is what you said).

I assume the volume you are working with is 5 gallons (the volume in the fermenter before adding the cherries).

Effective OG = (62*5 + 33)/final volume.

Lets assume the 10 cans total 1 gallon (to keep it simple)

Effective OG = (62*5 + 33)/6 = (310+33)/6 = 343/6 = 57. The effective gravity would be 1.057 .... yes, lower than you started with.

To get the actual gravity after addition of the fruit, you would do the same calculation replacing the 62 with 12 (gravity before adding sugars was 1.012). Using the same volumes assumed before, gravity = (12*5+33)/6 = 93/6 = 15.5, or gravity = 1.016.

Quick update on this brew. I racked off the cherries on Saturday and bottled (god, how I hate bottling) the batch. I had about 4 oz left and gave it a try. It's pretty darn good! I would imagine age will do nothing but improve the flavor, but it had some funk, had some sour and actually kept some of the goodness of my original brown ale.
