Derived Unit
In the SI International System of Units, a unit derived from one of the seven base units of length (meter), mass (kilogram), time (second), electric current (ampere), thermodynamic temperature (kelvin), amount of substance (mole) and luminous intensity (candela).
Thus, the derived unit of electrical resistance (ohm) is derived from length, mass, time, and electric current -
Ω = m2·kg·s-3·A-2
