Therefore the formula to calculate the risk for the fetus to be affected is: 1 x 1/50 x 1/4 = 1/200. How to convert human dose to animal dose? The common perception of scaling of dose based on the body weight (mg/kg) alone is not the right approach. Advances in less-lethal technology offer the promise of more effective control over resistive suspects with fewer serious injuries. If it does, as berkeman mentioned, I would like to know how it affects the general formula V = RI and how it would "adjust" the real value of current or voltage to. Humans should drink about 11. That’s because both SARS and the new outbreak are zoonotic, meaning these diseases started in animals before spreading to humans. In plain English, this LD50 statement says that a single oral dose consisting of 250 mg of aniline will kill, on average, one-half the population of 1-kg rats. 450 mg/Kg * 80 Kg gives an adult whole-body LD50 of 36 grams.
