398528 / 1024 = 389.18
Its always 1024 between different types of bytes, not 1000.

Its because things like bytes work in powers of 2. Hence why you get 256MB of memory, 512MB of memory etc. A kilobyte is 2 to the power of 10, hence 1024 bytes to a kilobyte. A megabyte would be 2 to the power of 20 (bytes/1024/1024=megabytes or kilobytes/1024 = megabytes and so on).

DarkBahamut is actually technically incorrect.
What he is explaining is actually mebibibytes and kibibytes.
Kilo and mega etc are all multiples of 1000.

1 kilobyte = 0.0009765625 megabytes

Not based on the popular use they arent, and that is what you encounter in an OS.

Actually your both right, depending on the context and conversion methods your relating to...
John, you went with the Decimal conversion, whereas DarkBahamut is relating to the Binary...
Binary representation would be 2^ (as DarkBahamut mentioned)
1 B = 1 byte
1 KB = 2^10 bytes = 1,024 bytes
1 MB = 2^20 bytes = 10,485,76 bytes
1GB = 2^30 bytes = 1,073,741,824 bytes
whereas the Decimal representation would be 10^
1 B = 1 byte
1 KB = 10^3 bytes = 1,000 bytes
1 MB = 10^6 bytes = 1,000,000 bytes
1GB = 10^9 bytes = 1,000,000,000 bytes
Both terms are technically correct when referencing it, but you need to state to which power you are referencing to...
Microsoft base there over the 2^ system primarily, hence they reference 1Gb as 1024Mb, etc... where storage manufacturers and such reference to the 10^ system, hence 100Gb HDD's are referenced as 1,000,000,000,000bytes in size.
Also a good reason why in Windows, the physical size of a drive is reported less than the size stated by the manufacturer.
PC BIOS's are all represented via Binary, which is more native to the machine language, so the total memory Steve has is 389Mb as mentioned, using 2^ (even though this is on his phone, it will still use binary conversion to represent memory)
