There are seven so called "base units" defined in the SI; meter, second, mol, ampere, kelvin, candela and kilogram [1].
Of these, mole and kilogram are dependent of the kilogram.
edit: this is a good, if maybe a bit misleading, illustration: http://www.nist.gov/pml/wmd/metric/upload/SI_Diagram_Color_April_2008-2.pdf http://www.nist.gov/pml/wmd/metric/upload/SI_Diagram_Color_A...

- delecti 11y ago> Of these, mole and kilogram are dependent of the kilogram. Did you make a typo? While it's technically true that the kilogram is defined by the definition of the kilogram, I just wanted to make sure.
- markild 11y agoNot a typo, but maybe a bit vague. I meant to say that the SI units both are dependant on the real world kilogram object.
- jessaustin 11y agoThe NIST chart is interesting. I'm surprised that charge is defined in terms of current, rather than the other way around.
