A system of measurement units in which the basic quantities are length, time, mass, electric current, thermodynamic temperature, luminous intensity, and abundance; corresponding basic units are meter (m), second (s), kilogram (kg), ampere (A), kelvin (K), candela (cd), and mole (mol). It has been given official status and recommended for universal use by the General Conference on Weights and Measures (1960, 1971). computers & web acronym
The International System of Units (abbreviated SI from the French phrase, Système 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. Abbreviation: SI See Also: SI Prefix
International System of Units (SI) is the unit system adopted by the General Conference on Weights and Measures in 1960 and recommended for use in all scientific and technical fields. It consists of seven base units (meter, kilogram, second, ampere, kelvin, mole, candela), plus derived units and prefixes.
A modern version of the meter-kilogram-second-ampere system of units, which is published and controlled by an international treaty organization (International Bureau of Weights and Measures).
the internationally accepted set of standards for measurement; the revised version of the metric system, adopted by international agreement in 1960.
An internationally agreed-upon system of units with which to measure properties such as time, mass, and length.
a complete metric system of units of measurement for scientists; fundamental quantities are length (meter) and mass (kilogram) and time (second) and electric current (ampere) and temperature (kelvin) and amount of matter (mole) and luminous intensity (candela); "Today the United States is the only country in the world not totally committed to the Systeme International d'Unites"
(SI) units based on the metric system of measurements
The coherent system of units adopted and recommended by the General Conference on Weights and Measures.
(Abbreviated SI in all languages.) A system of physical units in which the fundamental quantities are length, time, mass, electric current, temperature, luminous intensity, and amount of substance, and the corresponding units are the meter, second, kilogram, ampere, kelvin, candela, and mole. It has been given official status and recommended for universal use by the General Conference on Weights and Measures. It is also known (in French) as Système International d'Unités.
The International System of Units (abbreviated SI from the French language name ) is the modern form of the metric system. It is the world's most widely used system of units, both in everyday commerce and in science.
