alt Hacker NewsI think your interface is a bit inconsistent, this is why people ask that question.
If you have
65mi in 12mi/h -> 19500s
then instead of
12h in s -> 43200s
you should have
12h in s -> 43200
Then a unit at the end should mean that not all dimensions have been reduced.
In the same vein, in the README, the "weird results" section should come after the "dimension removal" section. The way it is now, the apparent "bug" comes before the feature.
You 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.
