dreifach It seems that for the below search, linked here, the internal calculation of the Wolfram Alpha integration is displaying instead of the actual desired output (being the hectarage).
nobodywasishere It works if you spell out "convert": https://kagi.com/search?q=convert+130310+km2+to+hectares conv is being interpreted as a convolution in this case. We'll see if W|A can handle this better.
dreifach nobodywasishere Got it, thanks! Yes, I can't say I've heard the word convolution used in this context before.
