Multivitamins nutrition facts label showing that the international unit of, for example, vitamins D and E correspond to different gram values. In pharmacology, the international unit (IU) is a unit of measurement for the effect or biological activity of a substance, for the purpose of easier comparison across similar forms of substances.
The enzyme unit, or international unit for enzyme (symbol U, sometimes also IU) is a unit of enzyme's catalytic activity. [ 1 ] 1 U (μmol/min) is defined as the amount of the enzyme that catalyzes the conversion of one micro mole of substrate per minute under the specified conditions of the assay method .
The insulin unit conversion is not consistent with his molar weight 5808 Da (g/mol): Using the insulin unit definition as 0.0347 mg/IU and human insulin molar mass 5808 g/mol: 1 IU = (0.0347*10^-3 g) / (5808 g/mol) = 5.974 * 10^-9 mol. But in other sources is written, that 1 IU of insulin is 6.945 * 10^-9 mol. Where is the mistake?

The name "katal" has been used for decades. The first proposal to make it an SI unit came in 1978, [6] [10] and it became an official SI unit in 1999. [6] [11] [12] The name comes from the Ancient Greek κατάλυσις (katalysis), meaning "dissolution"; [13] the word "catalysis" itself is a Latinized form of the Greek word. [13] [14]
Here's a first stab at a table, which should eventually be posted to the main article. 375 mg = 5,250 FCC units; 200 LAC = ??? 1 Lac. U. = 1 ALU = 1 FCC unit. It is more difficult to give an exact equivalence between milligrams (mg) and FCC units, but 125 mg should be sufficient as several companies list it as equal to 1750 FCC units.
