What is the SI system of units?

The SI system of units, short for the International System of Units, is a globally recognized measurement system used in science, industry, and everyday life. It was established in 1960 and serves as the modern version of the metric system. The SI system is based on seven fundamental units, known as the SI base units, which include the meter for length, kilogram for mass, second for time, ampere for electric current, kelvin for temperature, mole for amount of substance, and candela for luminous intensity. These base units are used as the building blocks for deriving other units of measurement, such as the newton for force or the watt for power. The SI system is characterized by its coherence and ease of use, promoting consistency and easy conversion between different units across various fields and disciplines.
