I try to simplify units to m^3/hr:
3 m^3 / s + 70 m^3 / hr
1. M-x calc-embedded
2. u c
- Old units: m^3/s
- New utis: m^3/hr
Result is OK, but units are wrong:
10870. m^3 / s

Hmm - the correct result 10870 m^3 / hr - so the result from Calc is
mathematically wrong. calc-embedded is not related, this happens in
"standard" Calc also.
Could you please make a bug report?
BTW, you should get the correct result when you first simplify units (u
s) and convert afterwards. Unit conversion seems to get confused
when the expression is a sum of summands in different units.
TIA,
Michael.
