Displaying incorrect conversion values in PowerToys Run when changing units

[LNKLEO]

no, that not a bug, but a correct answer.
you must have misunderstood Gib/Mib/etc. and Gb/Mb/etc.

Short story is: 10^2 = 1000 and 2^10 = 1024. A long, long time ago these were mixed up, meaning a kilobyte is/was 1024 bytes, while "kilo" should mean 1000. Nowadays, we invented the term kibibytes. Not even talking about the combination of the two types mentioned on storage devices...

It's actually bad practice of Microsoft to keep using the wrong unit, like, everywhere.
Also: MicrosoftDocs/microsoft-style-guide#392

Not sure if it was ever a mix up. Computer use base 2 not base 10. It is standard practice to refer to a kilobyte to be 1024 and not 1000.

@TheJoeFin

1. Just because it's done, doesn't mean it's right! Microsoft is downright wrong.
2. How do you explain Mbps (Megabits, 1000000 bits)

The standards bodies have deprecated this usage of the megabyte in favor of a new set of binary prefixes, in which this quantity is designated by the unit mebibyte (MiB).

1. I'm not arguing right vs wrong. It is semantics "mix up" vs "made different choices"
2. I don't haha

@Jay-o-Way The initial screenshot show 1024 MB being reported as 1.024 GB. This would be correct to you right?

[Jay-o-Way]

Just a short rant against Microsoft, haha. Conclusion for this issue is valid: non-issue.

[kwhur]

It's been over 20 years since the standards were established... I didn't know because I've only been using Windows OS. Thanks for letting me know

I never realised I am duplicating.. sorry!
I think #33026 should be merged - is that a thing for issues?

[Raf-UJ]

Since PowerToys is uniquely Microsoft related product I would love to hear your thoughts on potentially "fixing the historical issue" and provide accurate results for both each time regardless of the query?
Mentioning both MB and MiB each will slowly educate more and more users "as a byproduct".
Maybe even a button pop-up?
I wasn't fully aware how bad it is until I had to make fresh partition inside the windows environment.

• please provide new partition size in MB
  me: 500000 MB > Next
• WHAT DO YOU MEAN 500000MB PARTITION IS ONLY 465.66GB?! 😡
• ugh, okay.. I know! PowerToys will surely give me an answer on how to make 500GB partition!
• me: [Alt+Space] > [ %% 500GB in MB ] > [Enter]
  PowerToys: [ 500000 MB ]
• nope...
