International System of Units

The International System of Units (SI) is a standardized system of measurement used globally. It provides a consistent way to measure physical quantities such as length, mass, time, temperature, and more. The seven base units 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). By using SI units, scientists, engineers, and everyday people can communicate precise measurements, ensuring clarity and reducing confusion across different fields and countries.
