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.

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 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.

1 gram = 1000000 micro gram 50 kilogram = 50 x 1000 x 1000000 = 50000000000 micro grams

None. 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.

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

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 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.

1 gram = 1000000 micro gram 50 kilogram = 50 x 1000 x 1000000 = 50000000000 micro grams

1000000 micro grams in 1 gram Therefore in 0.21 grams we will have 210000 micro grams

1 gram = 1,000 milligrams so 1/2 gram = 500 milligrams

There are 1000 micrograms (mcg) in 1 gram.

None. 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.

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.

1 gram = 1,000 milligrams = 1,000,000 micrograms so 9 grams = 9 million micrograms.

1 microgram is 0.000000001 kg

There are one million micrograms in one gram.
