an IU is not a standardized unit that can be converted to mg with a single formula. IUs means something different for each item (usually vitamins) it is used for. So for one vitamin you could have 1000IUs and it is 10mg, whereas 10mg of another vitamin is only 100IU.
Converting IU to mg is very difficult. Mass equivalents are different for every vitamin, and this must be determined first. For example, vitamin A has the IU biological equivalent of 0.3 mcg retinol, or of 0.6 mcg beta-carotene.
The current RDA for Vitamin A is approximately 900 mcg, which is 3000 IU.
To convert, multiply the IU figure by 9/30 (or to get a very rough estimate, by 0.3).
I believe an iu (international unit) is equivelant to a mg (milligram).
Ans: 0.3 mg = 1,200 i.u...... 1 mg = 40,000 iu
how can convert 100 mcg B12 in mg
30.12 mgFom IU to mcg: 50000 IU/1.66 = 30120 mcgFrom mcg to mg: 30120 mcg/1000 = 30.12 mg Final AnswerFrom USDATo convert Vitamin A as beta-carotene:From IU to mcg: IU/1.66 = mcgFrom mcg to IU: mcg * 1.66 = IUSource http://dietarysupplementdatabase.usda.nih.gov/ingredient_calculator/help.php#q2Ther are 1000 mcg in a mg so to convert to miligrams you have to divide the micograms by 1000.
To convert 300 mg to 2000 IU you need to first convert the milligrams to micrograms (1,000 mcg is equal to 1 mg). Next, you need to determine what one IU represents.
converter 1mg vitamin B6 to IU ?
How can I convert from international units (IU) to milligrams or micrograms?Generally speaking, you can't. IU's measure the potency of a drug, not its mass or weight.

15 I.U. Vitamin E = 10mg, so 400 I.U. would =266.67 mg. (400/15x10=266.67). The World Health Organization sets the I.U. (International Units) for some medications, and vitamins, each of these has a different I.U. to mg ratio, and you have to find a reference to this ratio to be able to convert I.U to milligrams. It depends on hat the Vitamin E is as, example dl-alpha tocopheryl or dl-alpha tocopheryl acetate, check the chart on the following link for more info
Keep in mind that conversions from IU to mg are specific for each vitamin, so this formula/answer is only applicable for Vitamin D. You first have to convert the 2,000 IU into mcg. Each IU of Vitamin D is equal to 40 mcg, so you divide 2,000 by 40 which equals 50. Then you have to convert the mcg amount into mg which you do by dividing the mcg amount by 100. In this case 50 divided by 100, which equals 0.5, which means that 2,000 IU of Vitamin D is 0.5 mg
