Re: mg/kg to ppm
Originally posted by Robert Fogtmg/kg is the same as ppm, so no conversion will be necessary.
mg/kg = 0.001/1000 = 0.000001 = 1/1,000,000 = ppm

Re: mg/kg to ppm
mg/kg is not equal to ppm. The conversion depends on the density of both substances. In other words, mg/kg is not mg of water to kg of water, it is mg of x in kg of y.

Re: mg/kg to ppm
Isn't it the case that "ppm" is a relative volumetric ratio, regardless of density, whereas "mg/kg" is a relative mass ratio?

On a volume or mole fraction ratio, we have insufficient info.
Actually, because it is clear that it is a mass ratio, 2 mg/kg is the preferred form, rather than 2 ppm, which is ambiguous.

If you have patient weight in pounds, multiply by 0.4536 kg/lb to get weight in kg. Then multiply by recommended dosing in mg/kg. That will determine how many milligrams to administer.
