I would say using the units attribute is the most natural way to go. It could be optional and then built on top of pint, which would make it rather easy to implement:

```

ureg is a pint unit registry

y = a/b y.attrs["units"] = ureg(a.attrs["units"]) / ureg(b.attrs["units"]) ```

which if I understand the codebase correctly could be added to DataArray._binary_op. Not sure if it is similarly easy for ufuncs, is that what __numpy_ufunc__ would be for?
