@ehsteve Well it is easy to convert but in a user written script where you are doing a computation on a quantity you still have to write code to handle it in the right units.

```python

myarray = np.random.random([10,10]) * u.deg

sarr = sunpy.somefunction(myarray)

sarr = u.Quantity(sarr, u.deg) #do we want users to have to do this?
<some code what expects arrays in degrees>

print(<result>)
```

Unless you explicitly convert to degrees before doing some operation it will get it wrong.
