Well, at the moment I don't know another way as defining the calc
variables on the lisp level:

#+BEGIN_SRC emacs-lisp
(setq var-foo 9.81
      var-x 3.14
      var-bar ...)
#+END_SRC

Note: `var-' is a special prefix for the calc variables `foo', `x',
...

And then something like

  src_calc{2*x}

is working.
