There are 1,000,000 uatoms in an atom, a fact which I frequently forget and/or second-guess. This repo contains a lot of programming to save myself a little bit of remembering.
go install github.com/tessr/uatom/cmd/uatom
go install github.com/tessr/uatom/cmd/atom
Convert atom to uatom:
$ uatom 123
123 atoms = 123000000 uatoms
Convert uatom to atom:
$ atom 1234567
1234567 uatoms = 1.234567 atoms
