Seven metric base units make up the foundation of SI. And Specific combinations of SI base units yield derived units. That's why the differ.
The SI has 7 base units: http://en.wikipedia.org/wiki/SI_base_unit Also, the SI has tens of derived units - perhaps hundreds of them, since you can combine the base units in many ways. Those units are ultimately derived from the 7 base units. For example, units for area, volume, speed, force, energy, pressure, electric charge, voltage, and many more, are derived from some of the base units. http://en.wikipedia.org/wiki/SI_derived_unit
In SI units, that would be the Newton.In SI units, that would be the Newton.In SI units, that would be the Newton.In SI units, that would be the Newton.
The principal SI units used to derive all other SI units are the base SI units. These are the units for physical quantities such as length, time, mass, electric current, temperature, amount of substance, and luminous intensity.
The abbreviation for the International System of Units is SI.

Whichever you like, depending on what units you are required to work with; the units for any other measures that you might want to combine (imperial or SI).

make it easy to understand
SI and metric are the same units.
International System of Units (SI)
The principal SI units used to derive all other SI units are the base SI units. These are the units for physical quantities such as length, time, mass, electric current, temperature, amount of substance, and luminous intensity.

most of the world does SI so more people can understand with it in SI units

SI units are more accurate than English system units
