Non standard units for area and volume

When using the “Architecture” format in Model Info → Units, the units proposed for Area and Volume make no sense.

For example, if I set the precision to 1/4 inch for length, I get a precision of 1/4 inch squared for area and 1/4 inch cubed for volume. This makes no sense. It should be decimal.

This problem is present since SU 2020 and I pointed it for SU 2021.
