I would like to download a list of Physical functions for Excell which may
be used in Formula by using the accepted symbol for that constant
The value Pi is already included as PI()
What I want is things like the gravitational Constant, The speed of light
etc. the latest SI unit values would be nice.
My simple Cassio Pocket calculator has this facility I expect a
sophisticated application like Excell to also have some easy method of
including SI Physical Constants in formula.
This might be as an ADD IN but eventually this service should be a
standard
part of Excel
