Are data units binary or decimal?

Do data units in, say, the settings menu adhere to the IEC 60027-2 standard?

The IEC 60027-2 standard defines kilo-, mega-, etc. to be purely SI prefixes, and designates a series of prefixes to be used with the binary values.

So,

&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbspDecimal &nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbspBinary
(kB) kilobyte &nbsp&nbsp&nbsp&nbsp= 103 B&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp(KiB) Kibibyte &nbsp&nbsp= 210 B
(MB) Megabyte = 106 B&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp(MiB) Mebibyte = 220 B
(GB) Gigabyte = 109 B&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp(GiB) Gibibyte = 230 B
(TB) Terabyte&nbsp&nbsp&nbsp = 1012 B&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp (TiB) Tebibyte &nbsp&nbsp= 240 B

Well, delightful. I can see the site didn’t even post it the way it showed in the preview. -_-

Sorry, but I don’t understand what you want to know?

What do you not understand, specifically?
