instance
Contains the formula of this UnitType if it is a derived type. For example, "force" is "l1m1/s2", or 1 degree of length, 1 degree of mass, and -2 degrees of duration.
Contains the symbol of the unit that is the "normal" for this unit type. The normals for most unit types are the standard SI units. For example, the normal for duration is the metric second, and the normal for mass is the metric kilogram.
Contains the a description of the unit type.
Contains the symbol of the unit factor, i.e. "M" for mega, "G" for giga, etc.
