I tried almost the same thing and received a 0 also - so I thought I was doing it wrong. Yippee for repeatable discoveries that may or may not be an error.

Hi Randal:


The label expression:


[% '1 inch to ' || (to_int( $scale )/12) || ' Feet'%]


must work... but I got "1 inch to 0 Feet". $scale help says: "This function is only available in some contexts and will be 0 otherwise". .... Which contexts?

Developers, please light us.

    I've had this question come up several times and I've done some
    digging but can't find an answer.

    In map composer I can set my scale (Feet) to 1:7920 which is 1
    inch to 660 Feet.

      * I can display a scale bar.
      * I can display scale text (1:7920)

    Can I display  "1 inch to 660 Feet"  through use of an expression?
    I've been manually typing it in and sometimes I'll change map
    scale and forget to change the typed scale.
