There are 1000 nanograms in a microgram. So you have to divide your answer by 1000. 100 nanograms is actually 0.1 micrograms.
So there are 1000 nanograms in a microgram. Therefore 2ug is 2000ng. 2000ng divided by 100 is 20. There is a 20x dilution factor. So for every ml of stock, you dilute with 19ml solvent (total volume of 20ml).
There are 100 micrograms in 0.1 mg.
There are 1000 micrograms in one milligram. Therefore, 100 micrograms is equal to 100/1000 = 0.1 milligrams.
There are one million micrograms to one gram. 100 micrograms is 0.0001 of a gram.
There are 100 micrograms in 0.1 grams.
You have to convert milligrams to micrograms here. Therefore 0.02mg is 20 micrograms. There are 5 x 0.02mg in 100 micrograms.
100 micrograms is equal to 0.0001 grams.
100 micrograms is equal to 0.1 milligrams.
There are 1000 micrograms in a milligram. Here, you must multiply by 1000. 100*1000 is 100,000 micrograms.
100 ng = 1000 mg
There are 10,000 micrograms in a centigram. You have to divide here. 100/10000 is 0.01 centigrams.
You have 1000 micrograms in a milligram. Therefore you have to divide by 1000 here. 100/1000 is 0.1 milligram.
