A gram is a measure of mass. ppm is a measure of concentration or the ratio of two masses (or even two volumes). The two measure different things and, according to elementary rules of dimensional analysis, comparing one with the other is not valid.

∙ 12y agoYes, micrograms per gram is the same as ppm. Ppm means parts per million. There are a million micrograms in a gram.
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.
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.
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
Ppm stands per parts per million. There are 1,000,000 micrograms in a gram. Therefore micrograms per gram is already ppm.
100 kg is equivalent to 100,000 grams. If there are 1 part per million (ppm) of a substance in 1 gram, then there would be 100 ppm in 100 kg.
1 percent of H2S is equivalent to 10,000 parts per million (ppm) since ppm is a way to express a concentration, with 1 ppm being equivalent to 0.0001%.
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.
Mcg (microgram) is a measurement of weight or mass equal to one millionth of a gram, while ppm (parts per million) is a measurement of concentration expressing the amount of one substance in relation to a million units of a whole. In other words, mcg specifies the weight of a substance, while ppm indicates how much of a substance is present in a larger quantity.
1000 ppm is equivalent to 1 milligram per milliliter.
10,000 ppm Solution Method: 1. A ppm = 1/1,000,000 = 0.000001 2. What you want to know is: how many ppm would = 1% 3. p * .000001 = .01 4. p = .01 / .000001 5. p = 10,000 You could also do it this way: 1. 1% of 1,000,000 = ppm = 10,000 ppm (but that method lacks a clear path to understanding). === previous answer's method: 1%=1/100=1000000/100=10000ppm.
There are 1,000 micrograms in 1 gram.
There are 1 gram in 1 gram. Each gram is equivalent to 1 unit of weight.
1 gram of copper is in 1 gram of copper.
1 mg/kg = 1 ppm 1 mg = 1000 micrograms (ug) so 10 ug/kg = 0.01 mg/kg = 0.01 ppm
