SI units
The International System of Units, commonly referred to as SI units, is a decimal-based system of measurement that has been adopted globally for its simplicity, clarity, and ease of use. Developed from the earlier Metric system, SI units provide a standardized way to express physical quantities such as length, mass, time, temperature, and more. The system is based on seven fundamental units: 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 to derive other units for various physical quantities, ensuring consistency and accuracy in scientific and everyday applications. The use of SI units facilitates international communication and collaboration in fields like Physics, Chemistry, and Biology.
