How do you convert ug per milliliter to copies per milliliter?

Answer 1

You need to know the "molar/molecular weight" (MW) of what ever it is you are measuring. The molar weight is the mass of one mole (6.02214×10^23 copies) of a substance. (By the way 6.02214×10^23 is known as Avagardo's number). So if one mole of a substance weighed 1 g, then in 1 ug there would be 6.02214x10^20 copies. Further, what you do is this: copies/ml = ug/ml x (MW/1000) x L MW is generally given as g/mol thus you need to divide by 1000 go get ug/mol. L is Avagardo's number.

Answer 2

To convert micrograms (ug) to copies, you need to know the molecular weight of the substance. Divide the amount in micrograms by the molecular weight to get the amount in moles, and then use Avogadro's number to convert moles to copies. Once you have the number of copies, you can express it per milliliter by taking into account the volume of the initial solution.
