I aquired an older standup 16 qf freezer. I have the temp steady at

as good as zero?

Here in the UK -18C is the recommended 'ideal' temperature for a freezer.

That's 0 degrees Fahrenheit (more or less!)

I recall about the same in USA for freezer chest. For frost free
refrigerator freezer section, closer to freezing point of water because
of frost free cycling.
