## What is the standard measurement system?

The current international standard for the metric system is the International System of Units (Système international d’unités or SI). It is a system in which all units can be expressed in terms of seven units. The units that serves as the SI base units are the metre, kilogram, second, ampere, kelvin, mole, and candela.
