Derived units of unit system
Get the derived units of a unit system by using
derivedUnits. Then, modify the derived units and create
a new unit system using the modified derived units. Available unit systems
include SI, CGS, and US. For all unit systems, see Unit Systems List.
Get the derived units of the
SI unit system.

Define the new unit system by using
SI base units.
bunits = baseUnits('SI'); newUnitSystem('SI_kN_mbar',bunits,newUnits)
ans = "SI_kN_mbar"
