If you are converting the mass of a substance from milligrams/kilograms (mg/kg) to parts per million (ppm), then the ratio is 1:1, and no conversion is necessary. Therefore, 1 mg/kg is the same as 1 ppm because 1 milligram is equal to 0.001 grams while 1 kilogram is equal to 1,000 grams. So, if you divide 0.001 by 1,000, then the result is 0.000001, which is a millionth of a gram, making it the same as 1 part per million.
This logic only works for mass conversions. If you are attempting to convert mg/kg of volume or moles to ppm, then the substances being used will change the outcome. In the case of both volume and moles, ppm is found by using the formula c/s where "c" is the volume or moles of the compound divided by "s," which is the volume or moles of the solution.Learn More
The unit ppm stands for parts per million, and it refers to how much of one substance by weight is present in a mixture with one million times as much of another substance. Only very dilute substances are measured in ppm, such as minor impurities in water or air.Full Answer >
