029 to worry about the various kinds of unit classes unless one wants to
030 design a more complex case.
031 
032 There are many units already predefined in the module. One may use the
033 `~astropy.units.core.UnitBase.find_equivalent_units` method to list
034 all the existing predefined units of a given type::
035 
036   >>> from astropy import units as u
037   >>> u.g.find_equivalent_units()
