Is your feature request related to a problem? Please describe.

I could not find out, in which units the constants of scipy.constants are.
I guess they are in SI notation, but I'd like to be sure, before I use these numbers.

Describe the solution you'd like.

Could you add either a general note, that all the constants are given in base units of the SI system, or add to every constant the relavant units (e.g. speed of light in vacuum in meters/second).

Describe alternatives you've considered.
