The same: there are 1000 micrograms/milligram and 1000 milligrams/gram! Why should you want to convert that way? There are:
1,000 mcg in 1 mg
1 million mcg in 1g
1,000 mg in 1g
1,000,000,000 mcg in 1Kg
1 million mg in 1 Kg
1,000g in 1 Kg
There are 1,000 milligrams per gram. 0.2 grams*(1000 milligrams/gram) = 200 milligrams
You cannot. The problem here is you have weight per area and you want to convert to weight per volume. You need a third dimension to the area to calculate this.
(Micrograms per litre)/(gram molecular weight of solute) = (micromoles per litre).
You have to know the concentration first. That will either be in grams per milliliter (or milligrams per milliliter), or it could be in moles per liter (molarity). If it's given in grams per milliliter, just multiply that number by 60 and multiply by 1000.If it's given in moles per liter, than first find how many moles in 60 mL by multiplying by 0.06, and then convert moles to grams using the molar mass of caffeine (194.19 grams per mole).See the Related Questions for how to convert moles to grams.
1 milligrams = 1000 micrograms 1 sq meter = 10000 sq cm 25 mg/sq m = 25 x 1000 / 10000 micro gm/sq cm = 2.5 micrograms/square cm
They are the same thing. You have to divide to convert micrograms to milligrams. You have to multiply to convert per litre to per metre cubed. these cancel out.
There are 1,000 micrograms (mcg) per milligram. So, multiply milligrams by 1,000 to get micrograms.
There are 1000 micrograms in a milligram. Therefore 2000 micrograms is 2 milligrams.
Ppm is parts per million. This is more commonly, milligrams per litre. To convert this to micrograms per metre cubed, you multiply by 1,000,000. 32593.86*1000000 is 32,593,860,000 micrograms per metre cubed.
micrograms to grams is divide by 1,000,000
There are 1,000,000 micrograms in each gram. You need to divide by 1000000. 250/1000000 is 0.00025 grams.
There are 1,000 milligrams per gram. 0.2 grams*(1000 milligrams/gram) = 200 milligrams
There are 1000mcg per milligram: 0.5mg = 0.5 x 1,000 = 500mcg
Parts per million means milligrams per litre or micrograms per millilitre. Therefore you do not need to convert as they are the same thing.
12 micrograms per mililiter
There are 1000 micrograms in a milligram. Therefore 5 micrograms is 0.005 milligrams.
There are 1000 micrograms in a milligram. Therefore 50 micrograms is 0.05 milligrams.
