I've no idea what your precise question is. Are you just asking for examples of units? – ACuriousMind Aug 12 '14 at 11:22

If you have a length, you can express it as

• 1 foot (ft)
• 32 centimeter (cm)
• 320 millimeter (mm)
• 0.32 meter (m)
• 12 inch (in)

The numbers are different, but the units are also. Together, they represent the same length in reality.

The SI base units are defined in various ways, see the origins.
