The SI has 7 base units. These units can be combined in an almost unlimited way to form other (derived) units. The Wikipedia article on "SI derived units" lists some examples.
What should you do to change a value in SI units to a value in U.S. customary units?
SI means "International System [of Units]" (from the French abbreviation).
they are units for scientist
The SI unit for velocity is m/s. Therefore the SI units for velocity squared would be m2/s2.

Yes, it can. The units are kg/m3, or related versions.
There are 7 base SI units and all other are defined using these 7 base units. See the related question below:[http://wiki.answers.com/Q/What_are_all_the_SI_unitsWhat are all SI units?]

Because SI units are globally recognised (with the exception of Burma, Liberia and USA). SI stands for 'System International' See the related link to WIkipedia for more information.
SI units of length, volume, and mass are related as follows: Length is measured in meters (m). Volume is measured in cubic meters (m^3) or liters (L). Mass is measured in kilograms (kg). These three quantities are fundamental measures in the SI system of units and are used to describe the physical properties of objects.

Meter per secondThere is no standard SI unit for velocity actually. It is a derived unit. Velocity is distance traveled per time together with the direction of motion. The SI unit of distance is the meter (m) and the SI unit of time is the second (s).So the units of velocity in SI units is meters/second (m/s), or ms-1See the Related Questions link to the left "What are all the SI units" for more information about SI units.CommentDerived units are SI units.
SI and metric are the same units.
