How to get list of all available units?

[engin-can]

Hey guys, how can I programmatically get a list of all available units?

[OrangeChannel]

import pint
ureg = pint.UnitRegistry()
list_of_units = set()
for x in dir(ureg):
    try:
        if isinstance((u := getattr(ureg, x)), pint.Unit):
            list_of_units.add(u)
    except:
        pass
list_of_units = list(list_of_units)

Unless there's some builtin way I'm not aware of.
