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.
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.
668 ppm stands for 668 parts per million. It is a unit of measurement used to describe the concentration of a substance in a solution or mixture. In this context, it means that there are 668 parts of a particular substance for every 1 million parts of the solution or mixture.
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.
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.
There are 1,000,000,000 micrograms in a kilogram. This actually means parts per billion. Parts per million would be mg/kg. So to get here, you need to divide by 1000.
Yes, micrograms per gram is the same as ppm. Ppm means parts per million. There are a million micrograms in a gram.
Ppm stands per parts per million. There are 1,000,000 micrograms in a gram. Therefore micrograms per gram is already ppm.
This question doesn't make sense. This is because the term parts per million means either weight per weight i.e. micrograms per gram or milligrams per kilograms, or weight per volume, i.e. milligrams per litre or micrograms per millilitre.
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.
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)
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 = mass of solute / mass of solution X 1 000 000
668 ppm stands for 668 parts per million. It is a unit of measurement used to describe the concentration of a substance in a solution or mixture. In this context, it means that there are 668 parts of a particular substance for every 1 million parts of the solution or mixture.
10,000 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.
