{{#invoke:Koordinatlar| coord }} : General function formatting and displaying
coordinate values.

{{#invoke:Koordinatlar| dec2dms }} : Simple function for converting decimal
degree values to DMS format.

{{#invoke:Koordinatlar| dms2dec }} : Simple function for converting DMS format
to decimal degree format.

{{#invoke:Koordinatlar| link }} : Export the link used to reach the tools

coordinsert

Injects some text into the Geohack link of a transclusion of {{Koordinatlar}} (if that text isn't already in the transclusion). Outputs the modified transclusion of {{Koordinatlar}}.
IF THE GEOHACK LINK SYNTAX CHANGES THIS FUNCTION MUST BE MODIFIED.

Usage:

    {{#invoke:Koordinatlar | coordinsert | {{Koordinatlar}} | parameter:value | parameter:value | … }}

Do not make Geohack unhappy by inserting something which isn't mentioned in the {{Koordinatlar}} documentation.
