For that sentence to make sense is impossible."If...blah blah blah, then you can add your weight to damage rolls."
So for this sentence it's important (and makes sense) that it be "82 kilograms" added to damage rolls and not just 82?
Because your weight doesn't have a defined automatic set of units. You obviously can't add your weight to damage rolls.
It would have to say "the value of your weight in kilograms"
