Steps to reproduce:
Search "234234324 bytes" or some random big number
It tells me how many megabytes is that. Which Google do.
I don't want to enter "to megabytes" because the human-readable unit scale could've been gigabytes/terabytes/etc. which is another step I have to think
Similarly I'd expect "234234 seconds" to tell me how many days is that. Google doesn't do that, but WolframAlpha has the answer I expect.
