     ;

=  (  light years ;  

=    light years ;

=    light years ;

=    light years ;

=    light years ;

=      light years ;

=    light years ;

Note:  We can "cancel out" BOTH of the units of  "km" ; 

        →  {since:  "km/km = 1 "} ;  and rewrite:

=    light years ;

=   " { 59 ÷ 9.46 } "  light years ; 

=     6.2367864693446089 light years.
