AI overview
The International System of Units is a standardized way of measuring things—like length, weight, and time—using agreed-upon units (such as meters and kilograms), prefixes (like kilo- and milli-), and consistent rules for how to use them. It matters because it allows people and countries around the world to communicate measurements clearly and compare scientific and commercial results with confidence.

The International System of Units, internationally known by the abbreviation SI (from its official French name, Système international d'unités), is the modern form of the metric system and the world's most widely used system of measurement. It is the only system of measurement with official status in nearly every country in the world, employed in science, technology, industry, and everyday commerce. The International Bureau of Weights and Measures (abbreviated BIPM from French: Bureau international des poids et mesures) coordinates the SI.
