I was actually thinking of diameter-radians when I wrote that, but I didn’t know what they were called, so somehow I didn’t make up a name.
For the record, I was also making up a name when I said “halfradians”. And now that I think about it, it should probably be “twiceradians”, because two radians make one twiceradian. Oops.
