User-defined units are derived from the built-in units by their declaration in the document. Later, this document can be added to the list of include files.

The units are defined based on the default dimension "m." Later, it is shown how they are used. When the result calculation is in progress, the necessary unit is selected.

These units serve as a basis for calculating exponent units:

The nearest result measure is selected automatically.

 

Units that are more complicated are composed from simple ones.
