1 GO (gigaoctet) équivaut à 1 000 000 KO (kilooctets).

Hello,

I just called my Virgin Mobile advisor to ask him a question:

How many kB are in 1GB and he replied "1000".
Not very sure about his answer, I'm asking you, dear internet users, for advice.

An example: Last month, I used +600,000 kB, so if I follow his reasoning, I used
600 GB? I think that's indeed impossible, even though I'm not an expert.

So, if you could help me, I need to know how many kB are in 5GB :)

Thanks, and have a good day/evening!

Configuration: Mac OS X Snow Leopard (10.6) / Firefox 12.0

Well, 1 GB = 1000 MB and 1 MB = 1000 KB
1 GB = 1,000,000 KB
Note: Mega is related to million
1 KB = 1,000 bytes
1 MB = 1,000,000 bytes

Merci beaucoup pour ta réponse, donc 5G = 5000 MB = 5,000,000 KB ? :)

Hello.

The formulas are simple!!!!!
1 byte = 8 bits (not to be confused with byte (English) = octet (French).)
1 kilobyte (KB) = 1,024 bytes
1 megabyte (MB) = 1,024 KB = 1,048,576 bytes
1 gigabyte (GB) = 1,024 MB = 1,073,741,824 bytes
1 terabyte (TB) = 1,024 GB = 1,099,511,627,776 bytes
1 petabyte (PB) = 1,024 TB = 1,125,899,906,842,624 bytes

Beware, the standards increasingly addressed to the mathematically challenged have led to a simplification imposed by disk manufacturers to artificially increase the size of their disks or because they are too stupid to work in hexadecimal; this has not been specified...............
But here is the official international standard!

one kibibit 1 Kibit = 2 p10 bits = 1024 bits
one kilobit 1 kbit = 10 p3 bits = 1000 bits
one mebibyte 1 MiB = 2 p20 B = 1,048,576 B
one megabyte 1 MB = 10 p6 B = 1,000,000 B
one gibibyte 1 GiB = 2 p30 B = 1,073,741,824 B
one gigabyte 1 GB = 10 p9 B = 1,000,000,000 B

With this rule, it's easy to see that a 500GB disk is actually only 465 GiB.

a "standard" that has existed since '98, which nobody has ever heard of and which is not taught in schools?

Goodness.

Yes, a standard that few have heard of and that is not taught enough.


That doesn't change the fact that outside of Windows, all OSes have long recognized the difference between kilo and kibi.

What shocks me the most is that it is not taught in school at that time.

I had to teach it to 2 teachers who didn't know.

Many teachers do not keep up to date and just rely on what they themselves have been taught, including mistakes, without looking further.

1GB=1000MB=1000000KB

Hello,

In 1GB, there are 1000 MB
In 1MB, there are 1000 KB

So 600,000 KB represents 600 MB or 0.6GB..

Therefore, in 5GB, there are 5,000,000 KB.

In general, we round like hombourgeois did, but that's not the exact value.

In computing, we count in powers of 2, not in powers of 10.

1KB = 1024B
1GB = 1024KB

The kibibyte is counted in powers of two.

The kilo, like all SI units, is counted in powers of 10.
