Browsing6853 We do not know what country the searcher is from. Also it is not obvious whether you want "40 inches" to be converted to yards (what google does) or cm (what I would expect)?
Some things can be done but this is not trivial and would probably require assembling a list of easy/no brainer ones we should consider. Also not sure about how many people actually use this short format, but it does sound like a lot of work.
