    Does anyone know how to modify the following field code which displays the area of an object in base units (millimetres squared) to have it display in (metres squared). I know you have to multiply by 1000, but where does this fit in, in the code below.

    %<\AcObjProp Object(%<\_ObjId 2130353528>%).Area \f "%lu2">%

    Any help greatly appreciated.

    Regards

    Like this may be

    (defun mm2mtr (a)
    (/ a 1000.0)
    )

    area of an object in base units (millimetres squared) to have it display in
    (metres squared). I know you have to multiply by 1000, but where does this
    fit in, in the code below.

    As far as i know, you can't do mathematical operations with fields.
