The International System of Units (SI) is system of units of measurements based around the number 10. 

SI Units

Example #1: The SI contains nine BASE UNITS that each represent a different kind of physical quantity. These are commonly used as a convention. 

The International System of Units (SI) provides 9 units of measurement as the foundation from which all other SI units can be derived. 

Derived Units are generated through mathematical relationships between the base units. They represent a combination of the base quantities.
