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.
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.
1 IU vitamin A Palmitate = 0.55 mcg Ex: 100 IU vitamin A Palmitate = 55 mcg ie multiply the IU by 0.55
10,000 IU of vitamin A is equivalent to 3,000 mcg.
1000 mcg per 100 IU
Alfacalcidol is a vitamin D analog, and its potency is generally measured in micrograms (mcg) rather than international units (IU). However, 1 mcg of vitamin D is equivalent to approximately 40 IU. Therefore, 0.25 mcg of Alfacalcidol would be roughly equivalent to 10 IU of vitamin D.
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.
800 IU of vitamin D is equivalent to 20 micrograms (mcg).
1 IU is the biological equivalent of about 0.667 mg d-alpha-tocopherol (2/3 mg exactly), or of 1 mg of dl-alpha-tocopherol acetate
