international system

A scientist uses the international system to measure a chemical sample.

Definition
  1. Proper noun:
    • International System of Units (SI): A globally accepted, coherent system of measurement units based on seven fundamental quantities: length (meter), mass (kilogram), time (second), electric current (ampere), thermodynamic temperature (kelvin), amount of substance (mole), and luminous intensity (candela). It is the modern form of the metric system.
Usage
  • The term "International System" is most commonly used as a shortened form of the full name "International System of Units." It functions as a proper noun referring to this specific scientific and technical standard.
  • It is often abbreviated as SI, from the French "Système International d'Unités."
Examples
  • Proper noun:
    • All measurements in the physics experiment were recorded using the International System.
    • The International System provides a universal language for science and trade.
    • Converting to the International System simplifies communication between researchers worldwide.
Advanced Usage
  • "SI units": This is the most frequent way to refer to the individual units within the system.
    • The newton (N) is an SI unit of force.
  • "SI prefixes": Refers to the standard set of prefixes (like kilo-, milli-, micro-) used to denote decimal multiples and submultiples of SI units.
    • A kilometer is 1,000 meters, using the SI prefix 'kilo-'.
Variants and Related Words
  • SI (abbreviation): The standard abbreviation for the International System of Units.
  • Metric system: A broader term for the decimal-based system of measurement; the International System is its modern, internationally agreed-upon version.
  • Système International d'Unités (French): The original French name from which the abbreviation SI is derived.
Synonyms
  • SI system
  • Modern metric system
Related Phrases
  • Base SI units: Refers specifically to the seven fundamental units (meter, kilogram, second, ampere, kelvin, mole, candela) upon which the system is built.
  • Derived SI units: Units formed by combining the base units according to algebraic relations (e.g., the watt for power, which is kg·m²/s³).
