I am not sure if I get this right. Let's say that the lethal dose is 1.3 mg/kg. If I get the math right, it means that the lethal dose for 140lbs would be around 83 mg?
I just substituted 2.2 lb instead of kg, doubled up the mg/lb til I reached the 140 lbs and it's around 83 mg per 140lbs, right?
What's the formula for that? Thanks!
