The value of this read-only attribute is derived from the current value of the Unit attribute. It will represent an equivalent system of units to the Unit attribute, but will potentially be simplified. For instance, if Unit is set to " s$\ast$(m/s)" , the NormUnit value will be " m" . If no simplification can be performed, the value of the NormUnit attribute will equal that of the Unit attribute.
