{{convert/round{{{?}}}|{{{1}}}|0.25|{{{3}}}|{{{4}}}|{{{j}}} }}-[[{{{n}}}|{{{n}}}]]

The Template:Convert/LonAonSon displays the converted result and wikilinked unit symbol (if any). If the amount is small (<6 long) then a non-breaking space separates the unit symbol, else a regular space. If the unit symbol {{{u}}} is not set (such as with "acre"), then it shows the hyphenated unit name {{{h}}} or else {{{n}}} when no specific hyphenated name has been defined.
