System Internationale

The International System of Units, known as SI (from its French name, Système International d'Unités), is the standard method for measuring things worldwide. It provides a consistent set of units, such as meters for length, kilograms for mass, and seconds for time, used in science, industry, and daily life. SI ensures measurements are precise and comparable globally, facilitating communication, trade, and technological development. It is maintained by international agreement and updates to reflect advancements, aiming to create a universal language of measurement that everyone can understand and trust.
