This question cannot be answered. ppm is a ratio: so many parts of one substance per million parts of another. That can only be converted into mcg if the relative masses of the two substances are known.

Ppm stands per parts per million. There are 1,000,000 micrograms in a gram. Therefore micrograms per gram is already ppm.
what is the difference between mcg's & ppm's? If you have 22 ppm's, how many mcg's would you need?
Yes, micrograms per gram is the same as ppm. Ppm means parts per million. There are a million micrograms in a gram.
Firstly there is no such thing as litre cubed. It is just litre. ppm means milligrams per litre, so you have 10,000 milligrams per litre. This is 10,000,000 micrograms per litre.
ppm means mg per litre. mg/l means 100ug/dl. Therefore there are 10 x 10 micrograms per decilitre in ppm. In other words, 10ug/dl is 0.1 ppm.
Ppm is parts per million. This is more commonly, milligrams per litre. To convert this to micrograms per metre cubed, you multiply by 1,000,000. 32593.86*1000000 is 32,593,860,000 micrograms per metre cubed.
1 mg/kg = 1 ppm 1 mg = 1000 micrograms (ug) so 10 ug/kg = 0.01 mg/kg = 0.01 ppm
Ppm is part per million, a microgram is one millionth of a gram, a litre of water approximates to 1000g. 1300 micrograms is 1.3 milligrams. One milligram is one thousandth of a gram, as one litre is one thousand grams, 1mg/L is 1ppm ( 1 000 X 1 000 = 1 000 000), so 1.3mg/L is 1.3ppm.
2 gm of soil contain 0.030ppm of chromium how can convert microgram
10 g is 10,000 mg and in 1 liter that would be 10,000 ppm. You need to have a volume in order to express the mass as ppm. In other words, 10 g NaCl cannot be expressed as parts per million unless you have the volume that it is in. If it's in a liter, then you will have 10,000 ppm.
1000. This is because ppm commonly means milligram per litre to a chemisty. There are 1000 micrograms per litre in 1 ppm.
