How do I calculate the calories for this ?

When I scan the barcode on a package of hamburger patties from the meat counter, it tells me that one 5 oz. patty is 310 calories. After I grill it, it weighs 2.88 oz. I think I should figure the calories, based on it's weight after grilling. In this case, 57% of 310 calories. Can someone please tell me if I am calculating this correctly and if I am not, advise me ? Thanks for any help.

    I would weigh it before you grill it. Most nutrition facts are based on raw weight.

    Weigh it raw. Half the calories don't evaporate or leave during cooking.

    Raw.

    The barcode should give you the stats for the item (or serving) as it exists in the package, not after whatever it is you're going to do with it.

    Doesn't this mean that the facts may not be the same after cooking? I'm just picturing a raw burger, in the package. After cooking it there's a lot of fat left in the pan or dripped onto the bbq coals...

    Yes, cooking meats that have a lot of fat that leave the meat changes the values. Attempting to estimate that becomes a exercise in futility, however. Differences in cooking time, temperature, etc. makes it very difficult to come up with a consistent estimate of what the cooked product is.

    The better practice is to use the raw meat value. You use a more consistent datapoint to start with, and at worst you're overestimating your calories eaten instead of underestimating.

    Really good point.

    I googled this, because I just couldn't believe that I had been doing it wrong all this time. I have been and this most likely why I do not see a big weight change. Good question!
