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.
1000 micrograms is 1 milligram. so this is 1 milligram per millilitre, i.e. 1000 milligrams per litre. Parts per million is milligrams per litre. Therefore there are 1000ppm in 1000 micrograms per millilitre.
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.
Parts per million is milligrams per litre. Which would be 1000 milligrams per metre cubed. This would also be 1,000,000 micrograms per metre cubed. There are 1,000,000ug/m^3 in every ppm.
No. 1 ppb = 1 ug/L or 1 microgram per liter. You can find conversion charts on the web (http://waterontheweb.org/resources/conversiontables.html) Yes, ng/mL is equivalent to parts per billion. While it is true that 1 ppb = 1 ug/L, it is equally true that 1 ng/mL = 1 ppb. They are the same sice 1 ng is 1/1000 of a ug and 1 mL is 1/1000 of a L. All that has changed is the units, but they remain equivalent.
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.
Well, honey, to convert micrograms per kilogram to parts per million, you need to multiply by 1,000. Why? Because there are 1,000 micrograms in a milligram, and 1,000,000 parts per million in a kilogram. So, it's just a matter of shifting those decimal places around to get the job done.
Yes, micrograms per gram is the same as ppm. Ppm means parts per million. There are a million micrograms in a gram.
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!
1000 micrograms is 1 milligram. so this is 1 milligram per millilitre, i.e. 1000 milligrams per litre. Parts per million is milligrams per litre. Therefore there are 1000ppm in 1000 micrograms per millilitre.
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.
300ng/ml is 300 micrograms per litre which is the same as 300ppb (parts per billion), or 0.3ppm (parts per million)
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.
Parts per million means milligrams per litre or micrograms per millilitre. Therefore you do not need to convert as they are the same thing.
Parts per million is milligrams per litre. Which would be 1000 milligrams per metre cubed. This would also be 1,000,000 micrograms per metre cubed. There are 1,000,000ug/m^3 in every ppm.
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.
You cannot.parts per million are a measure of concentration while micrograms are a measure of mass. The twomeasure different things and, according to the basic rules of dimensional analysis, conversion from one to the other is not valid.You cannot.parts per million are a measure of concentration while micrograms are a measure of mass.

No. 1 ppb = 1 ug/L or 1 microgram per liter. You can find conversion charts on the web (http://waterontheweb.org/resources/conversiontables.html) Yes, ng/mL is equivalent to parts per billion. While it is true that 1 ppb = 1 ug/L, it is equally true that 1 ng/mL = 1 ppb. They are the same sice 1 ng is 1/1000 of a ug and 1 mL is 1/1000 of a L. All that has changed is the units, but they remain equivalent.
