The word “dedicated” does not correspond to verifiable facts, since `units` can do dimensionless / unitless calculations just fine; it is already a calculator with units built-in, and the example you provided only intensifies the impression that `qalc` and `units` are equivalent. IMO a proper pro-tip for `qalc` would need an explanation why one should prefer it over `units`.
