Danbooru

What KB measure does Danbooru use?

Posted under General

So i was downloading post post #2817196 and got rather curious about the filesize Windows and Firefox were displaying me vs the one displayed in Danbooru.

So i know for a fact Windows/Firefox use KB measures in the order of 1024 units, the post in question has a total of 1 039 428 bytes, and these are the measures i got:

Windows : 0,99 MB (1039428/1024/1024 Rounded)
Firefox : 1015,7 KB (1039428/1024 Rounded)
Danbooru : 1020 KB

Which measure is Danbooru using exactly? At first i thought it was using 1 KB = 1000 Bytes, but that doesn't match either since it goes around 1039,4 KB.
