There can be no equivalence.
A milligram (mg) is a measure of mass while parts per million (ppm) is a ratio of the mass of one substance relative to the mass of a mixture of that and other substances. It is a pure number and according to basic principles of dimensional analysis, any attempt at conversion from one to the other is fundamentally flawed.
