(International System of Units)
(modern metric system)

SI indicates the International System of Units, the current well-accepted metric units. The system offers refined definitions for a basic set of units (meter, kilogram, second, kelvin, mole, and candela) and a system of derived units. While the most common metric units predate the system, some of the derived units, especially for Electromagnetic measurement there are non-SI units also in common use, e.g., for Magnetic Flux Density, in addition to the SI unit, the Tesla, there is a non-SI (CGS) unit the Gauss still in use.
