Hallo Michael, thanks for the pointer to http://orgmode.org/org.html#Formula-syntax-for-Lisp - it was very helpful for my understanding.

Hm. I still got #ERROR. I reduced my issue to calculate the float (for hours) without multiplying it with "value": | time [h:m:s] | value | product | |--------------+---------+---------| | 09:15:00 | 2.54321 | #ERROR | #+TBLFM: @2$3='(org-time-string-to-hours $1) #+TBLFM: @2$3='(org-time-string-to-hours $1);L #+TBLFM: @2$3='(org-time-string-to-hours "$1");N ... each of the TBLFM results in the same error. At this stage, $2 is not my problem any more.
