Question

How can I convert from international units to milligrams or micrograms?

Answer 1

Hint: To convert between international units (IU) and micrograms (mcg) and milligrams (mg). Commonly the amount of micrograms or milligrams (mg) in a medication or vitamin supplement.

Complete step by step answer:
To understand this question, firstly we should know about the international unit (IU).
International units are a unit commonly used in the measure of front medications, vaccines and vitamins. The volume or mass that makes up one international unit is dependent on the concentration of the substance and therefore varies from substance to substance depending on what we measured.
If we want to find out how many micrograms and milligrams are $$1U$$ of our medication. We directly contact the drug manufacturer. Now, converting from mg or mcg to Iu for vitamins.
Vitamins A $$\to$$ International units (IU) is the biological equivalent of $$0.3$$. Mcg retinol or of $$0.6$$ mcg beta-carotene.
Vitamin Calculate $$\to$$ IU is $$50mcg$$ L-ascorbic acid.
Vitamin A $$\to$$ IU is the biological equivalent of $$0.025mcg$$ cholecalciferol.
Vitamin E $$\to$$ IU is the equivalent of about $$0.67mg$$ d-alpha tocopherol, or $$0.9mg$$ of dl-alpha tocopherol, or $$0.9mg$$ of dl-alpha tocopherol.

Note: Conversely, I have a soft get capsule that contains $$\text{500IU}$$ of vitamin A as retinol. Then to convert this is mcg, then I would multiply it by $$0.3$$.
$$500\times 0.3=150mcg$$
