Yes, micrograms per gram is the same as ppm. Ppm means parts per million. There are a million micrograms in a gram.
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.
1 ppm = 1 part per million = 1 gram per million grams = 1 gram per 1000 kilograms = 1 gram per ton. So the two are equivalent and conversion is redundant.
The two are unrelated. ppm means "parts per million", so the amount of grams for 1 ppm will also depend on the size of the sample. For example, if you have a sample of one ton, 1 ppm (a millionth of it) would be 1 gram; if your sample has a mass of one kilogram, 1 ppm would be 1 milligram, etc.
ppm stands for parts per minute.
by "ppm" I assume you mean "parts per million". 30 percent means 30 per 100, and 1,000,000 (a million) divided by 100 is equal to 10,000. This is the ration between ppm and percent. 30x10,000 is equal to 300,000, so 30 percent is equal to 300,000 ppm
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.
1 gram per tonne is 1 ppm. So 250 grams is 250 ppm. A tonne is a metric tonne, 2214 pounds
1 ppm = 1.33 µg/m3
1000. This is because ppm commonly means milligram per litre to a chemisty. There are 1000 micrograms per litre in 1 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.
1 ppm = 1 part per million = 1 gram per million grams = 1 gram per 1000 kilograms = 1 gram per ton. So the two are equivalent and conversion is redundant.
what is the difference between mcg's & ppm's? If you have 22 ppm's, how many mcg's would you need?
No. Micrograms per millilitre is exactly the same as ppm. There 0.5ppm is 100 times smaller than 50ppm.
Grams and liters are different units but for the sake of argument lets imagine that we are talking about milliliters of water.One microgram (1 mcg) is a millionth of a gram.One milliliter (1 ml) has a mass of 1 gram (water which I guess is relevant here)1 / 118 = 0.00847 ppm or 8.47 ppb (parts per billion) but the microgram measurement only had one significant figure so we really should round off to:0.001 ppm (10 ppb)
if it is water 1000 ppm = 1 mg/ml
