2 gm of soil contain 0.030ppm of chromium how can convert microgram
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.
Oh, dude, it's like converting microgram per gram to parts per million (ppm) is a piece of cake. All you gotta do is multiply micrograms per gram by 1000 to get parts per million because there are 1000 micrograms in a milligram. Easy peasy, lemon squeezy!
Yes, micrograms per gram is the same as ppm. Ppm means parts per million. There are a million micrograms in a gram.
To convert micrograms per square centimeter (ug/cm2) to parts per million (ppm), you need to know the density of the substance in question. First, you convert ug/cm2 to micrograms per cubic centimeter (ug/cm3) by dividing by the thickness of the material in centimeters. Then, you convert ug/cm3 to milligrams per cubic centimeter (mg/cm3) by dividing by 1000. Finally, you convert mg/cm3 to ppm by multiplying by the density of the substance in grams per cubic centimeter and then by 1,000,000.

Just as with a percentage, you have to ask, or ask yourself, "percentage of what? or ppm of what?" You divide the 0.5 microgram by whatever you want to compare it to, for example, the body weight.
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.
To convert micrograms per 100 sq cm per day to parts per million (ppm), you would need to know the density of the material in question. Once you have the density, you can use the formula: ppm = (micrograms per 100 sq cm per day * 10,000) / density. This will give you the concentration in parts per million.
To convert from parts per million (ppm) to micrograms per cubic meter (μg/m³), you need to know the molecular weight of the substance in consideration. Use the formula: μg/m³ = ppm * (molecular weight) * 24.45. This formula assumes typical conditions of temperature and pressure.
0.5Mm = 50 PPM
Multiply ppm by 10000.
