Physconst command, do you have something better?

I have find that:

1- physconst it is terrible, only 3 "constants",

2- boltzman constant has a wrong number.

Did someone wrote something better? Could you share it? If not I shall make something but before applying time to it I was looking for a previous solution.

Thanks to all.

Regards

Mariano
