Field value formatting - square

[Dawid]

Even though it’s a specific question, I would also like to have a thread where we can show some interesting and useful patterns for value formats and labels.

Right now I have a Area measure that has two options km2 and mi2.

First thing is that I’m trying to achieve superscript in value_format to show the value as 1000.34km2 but I believe no HTML or anything is allowed there.

Second part is the label. Right now I have Area [km2] and then Area [km2] AVG but it looks clunky to me. What do you guys use in practice?
