Cannot convert sq m to sq ft. But we can convert sq ft to sq m if 1 sq ft is typed in krunner it shows converter. If 1 sq m is typed krunner shows nothing.
It works when I type "1 square meter", so I suspect the issue is that "sq m" is not accepted when it should be. Would you like to submit a merge request to fix this? It's quite simple: you just need to add "sq m" (and maybe also "square m" to https://invent.kde.org/frameworks/kunitconversion/-/blob/master/src/area.cpp#L144 I can help, if this is the first time you've ever done such a thing.
