There are 1000 micrograms (mcg) to a milligram (mg).

Consumers most often see IU's on the labels of vitamin packages: in standard preparations the equivalent of 1 IU is 0.3 microgram (0.0003 mg) for vitamin A, 50

micrograms (0.05 mg) for vitamin C, 25 nanograms (0.000 025 mg) for vitamin D, and 2/3 milligram for (natural) vitamin E. Please note: for many substances there is no definite conversion between international units and mass units (such as milligrams). This is because preparations of those substances vary in activity, so that the effect per milligram of one preparation is different from that of another.

Most vitamins are based on the IU values, so why do you want to convert them when you do not buy them that way? To do some further research on your vitamin choices, visit the following web site: http://www.changingshape.com/resources/references/vmchart.asp

IU stands for International Unit, which used to be the method of measurement for Vitamin A. It has since changed to ug (micrograms) of RAE, which stands for Retinol Activity Units. Converting from IU to ug of RAE varies depending on the form of Vitamin A you're talking about. For most supplements however, it averages that 1 IU = 0.15 ug of RAE.

5 mcg is equal to 0.005 mg.

There are 5000 mcg in 5 mg. This conversion is based on the fact that 1 milligram (mg) is equal to 1000 micrograms (mcg).

1000 mcg = 1 mg so 5000 mcg = 5000/1000 = 5 mg. Simple!

5000 mcg is a non-standard abbreviation for 5000 micrograms, which is 5000Âµg, equivalent to 5 mg (milligrams). There are 1000 micrograms in a milligram.

1000 mcg=1mg

An mcg is a microgram, or 10^(-6) of a gram. An mg is a milligram, 10^(-3) grams. Thus 1 mg is equal to 10^3, 1000 mcg.

5 mg

six and two thirds tablets of 750 mcg = 5mg

1000 mcg = 1 mg and 1000 mg = 1 g 1,000,000 mcg = 1 g 5,000,000 mcg = 5g So you will need 5,000,000 / 5,000 = 1,000 tablets

1 mg = 1 000 Î¼g The answer is 5 000/3 = 1 666 doses

To convert from 400 mcg to mg, you divide by 1000. So, 400 mcg is equal to 0.4 mg. Therefore, 10 tablets of 400 mcg are equal to 1 tablet of 4 mg.

5mg/30mcg = 5000mcg/30mcg = 5000/30 = 166.66...
