Variable: org-table-formula-constants
org-table-formula-constants is a customizable variable defined in
org-table.el.gz.
Value
nil
Documentation
Alist with constant names and values, for use in table formulas.
The car of each element is a name of a constant, without the $ before it.
The cdr is the value as a string. For example, if you'd like to use the
speed of light in a formula, you would configure
(setq org-table-formula-constants '(("c" . "299792458.")))
and then use it in an equation like $1*$c.
Constants can also be defined on a per-file basis using a line like
#+CONSTANTS: c=299792458. pi=3.14 eps=2.4e-6
