Best Answer

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.

There is 1 ppm in 1 microgram/milliliter.

1 ppm = (liquid) 1 milligram/liter = 1 microgram/milliliter.

1 ppm = (solid) 1 milligram/kilogram = 1 microgram/gram

Yes, micrograms per gram is the same as ppm. Ppm means parts per million. There are a million micrograms in a gram.

1 milligram = 1,000 micrograms 1 microgram = 0.001 milligram

Type your answer here... yes

1 part per million, used to describe how many of one type of particle you will find amongst another type of particle

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.

Parts per million means milligrams per litre or micrograms per millilitre. Therefore you do not need to convert as they are the same thing.

There are 1000 micrograms in one milligram.

Yes. The equivalence between weight and volume is usually gram to millilitre. Therefore Dividing gram by a million gets you to microgram and converting millilitre to litre involves multiplying by 1000. So 1,000,000 x 1000 is a billion. i.e. parts per billion.

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.

There are 1000mcg (micrograms) per milligram.

1000. This is because ppm commonly means milligram per litre to a chemisty. There are 1000 micrograms per litre in 1 ppm.

1 milligram = 1,000 micrograms 1 microgram = 0.001 milligram

This involves a multiplication of 1000. This is because a microgram is 1/1,000,000 of a gram and a nanogram is 1/1,000,000,000 of a gram. Therefore there are 1000 nanograms in a microgram.
