Frequently Asked Questions
Why does IU to mg vary by substance?
International Units (IU) measure biological activity, not weight. For example, 1 IU of Vitamin A is a different weight than 1 IU of Vitamin D.
How do I convert moles to milligrams?
To convert moles to mg, multiply the number of millimoles (mmol) by the molecular weight (g/mol) of the substance.
