I have never seen vitamin B-12 measured in (I.U) international units. It's almost always measured in micrograms.

From what I've read, 2.4 mcg per day, is reportedly the FDA's recommended dietary allowance (RDA) for vitamin B12.

The conversion charts that I've come across supporting MCG to IU only pertain to the following vitamins: A, B1 through B6, C, D & E.

Perhaps contacting a local pharmacy may be your best bet?
