Answer / naresh tondepu
mcg is microgram, which is just a unit of mass like gram,
mg etc.
whereas ppm (parts per million) is concentration i.e no of
units per unit volume, like mg/mL etc.

PPM:
This is a way of expressing very dilute concentrations of
substances. Just as per cent means out of a hundred, so
parts per million or ppm means out of a million. Usually
describes the concentration of something in water or soil.
One ppm is equivalent to 1 milligram of something per liter
of water (mg/l) or 1 milligram of something per kilogram
soil (mg/kg).
mcg:
mcg = microgram = 1/1000 of a mg (milligram) There are one
thousand micrograms in one milligram.
Hardly we can say there is no much difference between these
two.
