alt Hacker NewsYou are right about this being confusing. I have thought about whether to adopt in as strict division or whether to be strict about in UNIT to have to produce UNIT. The first one will not resolve the issue of Umits selecting becquerel or Hz to represent N/s, but the second is not as much fun.
I think the behaviour is good as it is, it is just the output display that should be consistent (as I suggested in my example).
