Google search results reverse the results

Google search results reverse the results   (08/14/2017, 4:11 PM)

I entered into a Google search, the request "Convert 1 psi to inches of water column." The Google results included two from convertunits.com. The first is titled, "Convert psi to water column [inch]," which is what I requested but, the numerical answer, 0.03627..., is wrong. That is the reverse conversion. The second is titled, "Convert inch of water column to PSI," which is the reverse conversion but, with the correct numerical answer, 27.67..., to my request.

Part of the confusion may be due to convertunits.com using the ambiguous phrase "Convert between PSI and inches of water column," rather "Convert from PSI to inches of water column." The word "between" does not indicate the direction of the conversion.
