Definition The International System of Units (SI) is the modern standardized metric system of measurement used worldwide. International System of Units (SI), international decimal system The International System of Units (SI) is the metric system’s modern form and the most widely used measurement system for science, technology, industry, and commerce. At the dawn of the 21st century it was the predominant unit system for science. The International System of Units is getting a makeover. It provides a coherent and universally accepted framework for The SI is made up of 7 base units that define the 22 derived units with special names and symbols, which are illustrated in NIST SP 1247, SI Base Officially known as the International System of Units (SI), the metric system is the international standard system of measurement units. Over time, advances in technology have resulted in more precise measurements, generating an evolution of definitions for the Système The International System of Units, internationally known by the abbreviation SI (Système International), is the modern form of the metric system.
