Question

300 iu's is how many milligrams?

Answer 1

International unit (IU) of WHAT will decide the answer to your question.

For most of the drugs, IU is defined in terms of their biological activity. Refer to attached wiki page to find IU to mg conversion of some common pharmacological agents.

For instance,

1 IU of Vitamin A = 0.3 micrograms = 0.0003 mg of retinol so , 300 IU of vit. A = 0.09 mg of retinol.

But it will vary depending on the drug under consideration.
