How do you convert chorionic gonadotrophin mcg to iu?

To convert chorionic gonadotrophin (hCG) from micrograms (mcg) to international units (IU), you need to know the specific potency of the hCG preparation being used, as different formulations can vary. Generally, 1 mcg of hCG is equivalent to approximately 2 IU, but this can differ based on the source. Therefore, the conversion would be calculated by multiplying the mcg amount by the specific conversion factor (e.g., 2 IU/mcg) associated with that preparation. Always refer to the product's labeling for accurate conversion information.
