@nealmcb I'm glad I'm not the only one who's been ticked off by this. I've always found it odd when Windows displayed something like 100.71 MB (105,600,322 bytes) and was never able to figure out why this was the case until I learned about the whole fiasco with binary vs. decimal units.

In 2009, Apple switched to standards-based prefixes for filesystems etc, to match disk drive manufacturers, i.e. GB = 10^9 bytes. eshop.macsales.com/blog/… Ubuntu changed in 2010 wiki.ubuntu.com/UnitsPolicy When will Windows catch up with reality? | |
| Mar 17, 2018 at 2:31 | comment | added | davidbak | The filesystem megabyte being $2^{20}$ bytes - maybe. Sometimes in the same OS you'll see "megabytes" (including decimal precision) being $10^6$ in some of the tools and $2^{20}$ in others. Most often in command line tools vs GUI tools, but I know of an OS where even different OS-provided GUI tools disagree on this... | |
