I use radiobuttons if the list of choices is small and static, like about 2 - 5 fixed entries. Comboboxes are better for larger lists, or if the user can add own entries, or if there's a chance that the program needs more entries later. IME, radiobuttons cause more visual distraction while comboboxes can be less obvious for less tech-savvy people. OTOH, comboboxes require two clicks. For your situation with units, I would probably go for radios if the user needs to change the units often and combos if radios would make the view more complex and less obvious. -- https://mail.python.org/mailman/listinfo/python-list
