byte sizes

[sandra ramos]

When calculating size formats to determine in bytes, what's the best way to calculate size, ie. to determine if a gig, meg, kilobytes.

[Steven E. Protter]

1024 bytes = a kilobyte
1024 kilobytes = a megabyte
1024 megabytes = a gigabyte
1024 gigabytes = a terabyte

Please forgive my spelling.

Hi,

1 KiloBytes = 1 * 1024 Bytes.
1 MegaBytes = 1 * 1024 KB = 1 * 1024 * 1024 Bytes
1 GigaBytes = 1 * 1024 MB = 1 * 1024 * 1024 * 1024 Bytes

[Patrick Wallek]

You're kidding, right?

If you have 123,456,789 bytes then:

1,234,567,890 byte / 1024 = 1,205,635.70 KB

1,205,635.70 KB /1024 = 1,177.38 MB

1,177.38 MB / 1024 = 1.15 GB

If you want to go a step further and get TB then:

1.15 GB / 1024 = 0.001 TB

Just be aware that some HDD manufacturers don't advertise by the true byte counts on their disks, they take the easy decimal way out of the whole argument, and just divide by nice round 10 base numbers.

Thanks guys for your responses!!

one last bit: (he he)

due to a recent court case, there are two definitions of Kilobyte, and the upward layers thereof.

1st: the classic defninition, above, where Kb=1024b.. etc...

2nd: the HDD manufacturer standard where Kilobyte=1000b and Kibibyte=1024b.
these names are

for the whole spectrum

here are links to a couple of calculators:


all on one page; used by many at our place:

this one requires Java:

quicky cut and paste chart:
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)
