Ppm stands per parts per million. There are 1,000,000 micrograms in a gram. Therefore micrograms per gram is already ppm.
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.
No, one percent is one part per 100. 1 ppm is equal to one part per 1,000,000. In other words, 1 PPM is 10,000 times smaller than 1%.
1 ppm is approximately 1gram per ton
Given that a liter of water does weight about a kilogram, there would be a million milligrams of water per liter, so yes, one milligram per liter does work out to be one part per million (ppm).
Write an equation representing the ppm concentration: ppm = mass solute (mg) ÷ volume solution (L) Extract the data from the question: mass solute (NaCl) = 0.0045 g. ... Convert the mass in grams to a mass in milligrams: mass NaCl = 0.0045 g = 0.0045 g × 1000 mg/g = 4.5 mg.
Yes, micrograms per gram is the same as ppm. Ppm means parts per million. There are a million micrograms in a gram.
1 ppm = 1.33 µg/m3
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.
2 gm of soil contain 0.030ppm of chromium how can convert microgram
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.
what is the difference between mcg's & ppm's? If you have 22 ppm's, how many mcg's would you need?
1 gram per tonne is 1 ppm. So 250 grams is 250 ppm. A tonne is a metric tonne, 2214 pounds
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)
