An international unit (IU) is NOT a fixed amount of micrograms. It is a measure based on the effect of a substance, so the same amount of IUs can be equivalent to different amount of micrograms, for different substances.
1 IU vitamin A Palmitate = 0.55 mcg Ex: 100 IU vitamin A Palmitate = 55 mcg ie multiply the IU by 0.55
To convert the units, it's important to know that 1 microgram (mcg) of vitamin B12 is equivalent to approximately 40 International Units (IU). Therefore, to equal 2.4 mcg of B12, you would need about 96 IU (2.4 mcg x 40 IU/mcg). Since 1000 IU is much larger than 96 IU, 1000 IU of B12 is far more than needed to meet the 2.4 mcg requirement.
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.
2400 IU is 50μg.
To convert 1000 mcg to IU, the specific conversion factor depends on the substance being converted. For example, for vitamin A, the conversion factor is often 3.33 IU per mcg. To find the equivalent IU value, you would multiply 1000 mcg by the conversion factor.

how can convert 100 mcg B12 in mg
An International Unit (IU) is a standardized measurement used to quantify vitamins A, D, and E. The conversion to micrograms (mcg) or milligrams (mg) varies for each vitamin. For vitamin A, 1 IU is equivalent to 0.3 mcg retinol. For vitamin D, 1 IU is equivalent to 0.025 mcg cholecalciferol. For vitamin E, 1 IU is equivalent to 0.67 mg tocopherol.
