1,024 Byte = 1 Kilobyte (KB)
1,024 Kilobyte (KB) = 1 Megabyte (MB)
1,073,741,824 Bytes = 1 Gigabyte (GB)
1 Gigabyte (GB) = 1,024 Megabyte (MB)

Thanks Guys xxxxxxxx Sandra

Depends who you ask ;-)

1000 = 1

As a rough rule of thumb, if you are selling then there are 1000 KB in 1 MB.

On the other hand, if you are buying you want to make sure you get the full 1024 KB which is the correct figure.

The confusion all stems from marketing people who are not especially known for letting small inaccuracies get in the way of a sale. It is easier for them to refer to 1000 KB as a megabyte than to work out the real figure as mentioned by Eric10 and Mike ® above

As justme rightly points out it's a slight spin on figures (bit like New Labour) so that, for instance, a hard drive apparently has a higher capacity than in reality. i.e. dividing capacity by 1000 rather than 1024 provides a superior GB level.

Er - It's not spin.

The internationally agreed terminology for Kb is 1000 bytes, and for Mb 1000Kbytes.

Only the computer industry has grown up with a different definition because basically of the ramifications of the binary numbering system. And in these terms Kb is 1024 bytes and Mb is 1024Kb.

Both are entirely correct - you just need to know which one is being used.

Hard Disk drive manufacturers agreed some time ago to use the standard (K = 1000) terminology, so that there is no confusion between the quoted figures of different manufacturers, and because it was felt more appropriate when discussing the storage of real data (rather than the internal workings of the computer), that the normal standard definition was better related to everday discussions.

After all, if you said it was 1 Kilometer to the next town, you wouldn't expect it to be 1024 metres, would you.

  Eric10 20:42 28 Jan 2004

No PS I wouldn't expect that, but then Kilometers are based on the decimal system while Kilobytes are based in binary so it wouldn't apply as there is no relationship between the two.

Metric multiplies by 10. 10, 100, 1000, 10000, etc.

Binary multiplies by 2. 2, 4, 8, 16, 32, 64, 128, 256, 512, 1024, etc. Oh! there's that 1024 again but I don't see 1000.
