As a physics student, I most often use Wolfram|Alpha to handle unit conversions. Here is an example that, in the past, Wolfram|Alpha would have handled correctly. Now it interprets the units instead as variables in the equation.
It seems like there's been a recent change (maybe 1-2ish months ago?) that has changed how wolfram alpha interprets units, and now many of these examples don't work unless the units are explicitly written out, whereas previously they worked even when not written out. Compare the following: units not written out, vs. units written out.
These changes seem to me to make the product strictly worse... is there anything I can do in the settings to revert back? What change was made that results in this different handling of units?
