1 mg/kg = 1 ppm 1 mg = 1000 micrograms (ug) so 10 ug/kg = 0.01 mg/kg = 0.01 ppm
Yes, micrograms per gram is the same as ppm. Ppm means parts per million. There are a million micrograms in a gram.
by "ppm" I assume you mean "parts per million". 30 percent means 30 per 100, and 1,000,000 (a million) divided by 100 is equal to 10,000. This is the ration between ppm and percent. 30x10,000 is equal to 300,000, so 30 percent is equal to 300,000 ppm
1 ppm is one part per million, or one millionth - percentage (which is latin for per hundred) wise, 1 ppm is .0001%
No, one drop is not necessarily equal to 1 ppm (parts per million). The concentration represented by 1 ppm refers to one part of a substance in one million parts of a solution, which depends on the total volume of the solution. The volume of a drop can vary based on its size and the liquid's properties, so the equivalence depends on the context and specific measurements involved.
