1 ng is 0.04 IU. So, to convert 12.5 microgram, multiply 12500 nanogram with 0.04; the required answer is 500 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.
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.

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.

400mg of vitamin D is equivalent to 10,000 IU (International Units). IU and mg are different units of measurement for vitamin D, with 1 IU equaling 0.025 mcg for vitamin D3. It's important to consider the measurement units when determining the appropriate dosage of vitamin D for supplementation.
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
1 IU vitamin A Palmitate = 0.55 mcg Ex: 100 IU vitamin A Palmitate = 55 mcg ie multiply the IU by 0.55
The conversion from international units (IU) to milligrams (mg) depends on the substance in question, as different compounds have different conversion factors. For example, for Vitamin D, 4000 IU is equivalent to about 100 mcg, or 0.1 mg. However, for other substances, the conversion can vary significantly. To get an accurate conversion, it's essential to know the specific substance involved.
1 mcg vitamin D (cholecalciferol) = 40 IU Let´s say you have 300 IU of vitamin D: 300 / 40 = 7,5 mcg vit. D Then you would have to convert 7,5 mcg to mg: 7,5 / 1000 = 0,0075 mg vitamin D.
3500 IU is equal to 1050 mcg (microgram) retinol (Vitamin A)
10,000 IU of vitamin A is equivalent to 3,000 mcg.
