Système International d'Unités (SI)

The Système International d'Unités (SI), or International System of Units, is the globally accepted standard for measuring physical quantities like length, mass, time, temperature, and more. It provides a consistent framework with specific base units such as the meter for length, kilogram for mass, second for time, and kelvin for temperature. Derived units are formed from these base units to measure other quantities, ensuring clear and precise communication across science, industry, and everyday life. The SI system promotes uniformity and accuracy worldwide, facilitating international cooperation and understanding in measurement.
