I know this might be considered correct behavior but usually if not always I want to act on it as a whole.
The separate units are most useful for display of length and also in modifier stacks 0.5 mm looks better than 0.0005m.

First turn on separate units:

Then move along Z axis by 1m 58cm:

Now if we /2 this input it only halves the cm part: {F7755114}

I'm not sure whether this should be considered a bug or a feature. With the current behavior you can do (1m 50cm)/2 to divide everything. However, if we would change the behavior to what you suggest, we could not divide individual units easily anymore. I don't really have a strong opinion on this issue though. Implementation wise, this could be a little bit tricky, but definitely solvable.

Maybe this should be treated as a feature request, not sure.

@WilliamReynish what do you think?

I have no strong opinion on that. At the very least, I would probably say that this isn’t a bug, but a feature request with some new downsides.
