2 gm of soil contain 0.030ppm of chromium how can convert microgram
Ppm stands per parts per million. There are 1,000,000 micrograms in a gram. Therefore micrograms per gram is already 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.

what is the difference between mcg's & ppm's? If you have 22 ppm's, how many mcg's would you need?
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.
There are 1000 micrograms in a milligram. To convert, you multiply by 1000. 25*1000 is 25,000 micrograms.
0.5Mm = 50 PPM
Multiply ppm by 10000.
There are 1000 micrograms in a milligram. To convert, you multiply by 1000. 0.077mg is 77 micrograms.
322 ppm = 0.0322%
1 GPG = 17.1 PPM
