You can't. It always uses the units of the spatial reference system your data is stored in.
What spatial ref are you using?

Hi list, Regarding the st_dwithin(geometry, geometry, float) function, I would like to know how can I pass the distance argument in kilometers. In our tests we have been using a dummy value of 0.003, but we don't even know which units it is in.
