[QUOTE="bobtomay, post: 1649734, member: 24160"] Math - Base 2 vs Base 10 - you can google it for more. [url]https://support.apple.com/en-us/HT201402[/url] ...... Apple changed OS X to use Base 10 instead of Base 2 calculations a few years ago to stop this question - which frankly was being asked all the time - even here in this forum, we saw this question practically every day - sometimes multiple times a day. Apple should have done it with iOS at the same time. OS X is, at this time, the only operating system that has been converted to use Base 10 while every drive manufacturer uses Base 10 in advertising their drive sizes. That is why you will always see the 1 GB = 1,000,000,000 bytes on the packaging. [/QUOTE]
