Thank you for the PR.

I think it breaks the buttons to navigate through pages in the resources interface (bottom right):

When a submissions file is stored, the standard used for Kilobytes (KB) is 1024 and not 1000.
https://github.com/codalab/codabench/blob/develop/src/apps/datasets/models.py#L67

In the change I have made, I use 1000.

// loop over n until it is greater than 1000
while(n >= 1000 && ++i){
     n = n/1000;
 }

Should this be changed to 1024?

So I guess right now we showing MiB, GiB, etc. instead of MB or GB.

Yes, maybe it is better to change this to 1024.

[ihsaan-ullah]

I think KiB, MiB, GiB are multiples of 1024 while KB, MB, GB are multiples of 1000.

my change is showing KB, MB, Gb.

OK then we can let it as it is, because the information provided is accurate.
