The international unit varies according to the substance. An IU is the amount of something that is needed to produce an effect which has been agreed upon as a standard. So, 1000 IU of Vitamin D has a different mass than 1000 IU of Vitamin C.

It is not a fixed number of mg. Rather, it varies from substance to substance. 1 IU is defined more or less on the basis of a substance's effects.

How many IUs equals 1 mg?

There is no direct conversion. The IU has a different value for every vitamin measured in those units.


How do you convert 5000 iu of vitamin A to mg?

To convert from International Units (IU) of vitamin A to milligrams (mg), you can use the conversion factor of 1 IU of vitamin A is approximately equal to 0.3 micrograms (ยตg). Therefore, 5000 IU of vitamin A is equal to approximately 1.5 mg.


What is an IU when measuring vitamins A D and E and how does it translate to mcg and or 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.


Vitamin e milligrams to international units conversation?

The conversion factor for vitamin E is 1.49. To get from IU to milligrams of alpha-tocopherol equivalents, divide by 1.49. Example: 30IU divided by 1.49 yields 20 mg alpha equivalents. To get from milligrams to IU, multiply by 1.49. Example: 10 mg alpha equivalents equals 15 IU (rounded up from 14.9).


1.25 mg would be equivalent to how may iu of vitamin d?

There is no direct conversion between milligrams (mg) and International Units (IU) for vitamin D because they measure different aspects of the nutrient. However, a common conversion for vitamin D3 is 1 microgram (ยตg) = 40 IU. So, you would need to convert the 1.25 mg dosage to micrograms and then calculate the equivalent IU based on this conversion factor.
