[name] Name of the conversion set
[conversion,conversion,...] Conversions for \part, \chapter, \section, etc.
[default] Default setting if no explicit conversion is set


The command defines conversion of internal counters.

The first argument is just the name which is used as argument for sectionconversionset in \setuphead, and for prefixconversionset in \setupcaption, \setupenumerations etc in MkII, and for numberconversionset for the same purpose in MkIV. The name of the conversion can be prefixed with the name of a sectionblock, e.g. \definestructureconversionset.

With the second argument you can set a conversion of the counter for the headings. The list always starts at the \part level and continues with \chapter etc. but it’s possible to leave entries empty.

With the third argument one can set a default value which is used when no value for a heading is set with the second argument.


% mode=mkiv


    [A,   % part: capital letters
     KR,  % chapter: small caps Roman
      ,   % section: none defined (use fallback)
     m,   % subsection: medieaval, a.k.a. oldstyle
     R]   % subsubsection: capital Roman

    [before={}, after={}, 


Be careful not to let a whitespace after myconversion, or it is taken as a part of it :

% mode=mkiv

\setupenumeration[% some setups
                  numberconversionset=questionNums % this does not work : add a comma or close bracket here
