Just as with a percentage, you have to ask, or ask yourself, "percentage of what? or ppm of what?" You divide the 0.5 microgram by whatever you want to compare it to, for example, the body weight.

To convert 0.5 micrograms of lead to parts per million (ppm), you need to know the total weight or volume of the substance the lead is in. Once you have that, you can use the formula: ppm = (micrograms of lead / total weight or volume of substance) * 1,000,000.

How many parts per million in 1000 micrograms per milliliter of iron in solution?

1000 micrograms is 1 milligram. so this is 1 milligram per millilitre, i.e. 1000 milligrams per litre. Parts per million is milligrams per litre. Therefore there are 1000ppm in 1000 micrograms per millilitre.


How do you convert micrograms per 100 sq cm per day to part per million?

To convert micrograms per 100 sq cm per day to parts per million (ppm), you would need to know the density of the material in question. Once you have the density, you can use the formula: ppm = (micrograms per 100 sq cm per day * 10,000) / density. This will give you the concentration in parts per million.


Derive the relationship between micrograms per meter cube and parts per million?

To derive the relationship between micrograms per cubic meter (μg/m³) and parts per million (ppm), we need to use the molecular weight of the substance. The formula is: 1 ppm = (Molecular weight in g/mol) / 24.45 * 1 μg/m³. This equation allows us to convert between the two units for a specific substance.


Is micrograms per ml equivalent to ppm?

Yes, micrograms per milliliter (µg/ml) is equivalent to parts per million (ppm) when referring to the concentration of a substance in a liquid. It signifies the amount of a substance per unit volume of the liquid.


How many ppm are in 1300 micrograms per liter?

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.
