“International System of Units”
International System of Units
The International System of Units (abbreviated SI from the French phrase, Systéme International d'Unités) is the most widely used system of units. It is the most common system for everyday commerce in the world, and is almost universally used in the realm of science.
In 1960, SI was selected as a specific subset of the existing Meter-Kilogram-Second systems of units (MKS), rather than the older Centimeter-Gram-Second system (CGS). Various new units were added with the introduction of the SI and at later times. SI is sometimes referred to as the metric system, especially in the United States, which still has not widely adopted it, although it is becoming increasingly common, and in the United Kingdom where conversion is only partial. SI is a specific canon of measurements derived and extended from the metric system; however, not all metric units of measurement are accepted as SI units.
