What is the meaning of international unit?
Why are international units used?
International units are used to quantify vitamins, hormones, some medications, vaccines, blood products, and similar biologically active substances. The goal of the IU is to be able to compare these, so that different forms or preparations with the same biological effect will contain the same number of IUs.
What are international units for vitamins?
The IU is an International Unit, usually used to measure fat soluble vitamins including Vitamin A, D and E. The conversion of IU to mg varies depending on the nutrient. One milligram of beta carotene = 1667IU of Vitamin A activity. 15mg of beta carotene = 25,000IU of Vitamin A activity.

What are the International System units?
Medical Definition of International System of Units . : an internationally accepted system of units based on the metric system and having the meter, kilogram, second, ampere, kelvin, mole, and candela as base units, the radian and steradian as supplementary units, and deriving all other units from these —abbreviation SI.
What is the basic unit in the International System of units is?
The kilogram is the only base unit of the International System of Units that includes a metric prefix. The litre (equal to a cubic decimetre), millilitre (equal to a cubic centimetre), microlitre, and smaller are common. In Europe, the centilitre is often used for liquids, and the decilitre is used less frequently.
