What is the sl unit?

The SL unit, or System International (SI) unit, refers to the standard set of units used in science and engineering for measurements. The SI system includes seven base units: meter (length), kilogram (mass), second (time), ampere (electric current), kelvin (temperature), mole (amount of substance), and candela (luminous intensity). These units provide a consistent framework for expressing physical quantities and facilitate communication across various scientific disciplines.
