So first off we need to convert milligrams to micrograms. 100mgx1000 is 100,000 micrograms. 40/100,000 is 1/2500 of a pill.
0.3 mg = 300 micrograms
There are 2.5 grams in 2500 mcg because 1 milligram (mg) is equal to 1000 micrograms (mcg).
There are 100 micrograms in 0.1 mg.
0.075 mg = 75 micrograms
4000 mcg (micrograms) equals 4 mg (milligrams)
130mg equals 130,000mcg (micrograms) * (1000mcg per mg)
60mg equals 60,000 micrograms (1000mcg per mg).
There are 1,000 micrograms in 1 milligram.
1 mg is equal to 1000 micrograms.
micrograms / 1,000 = mg mg x 1,000 = micrograms
1 gram = 1,000 mg 1 mg = 1,000 micrograms
