4.7 Go est l'abréviation en français pour gigaoctets, tandis que 4.7 GB est l'abréviation en anglais. Les deux se réfèrent à la même quantité de données, où 1 Go = 1 GB.

Yes, but which blank DVDs are you talking about? DVD+/-R? Which brands?

120 or 240 minutes is a vague indication, and by the way, what kind of minutes are those? Video, audio,...?
It all depends on the compression format! For example, Mpeg2 or wave formats take up more space than Dvix (Mpeg4) or Mp3!

In any case, rest assured, 4.7GB is equal to 4.7GB.

Enjoy.

Attention à ne pas confondre GB, Gb (majuscule sur le b) et Go, en effet Go = GB c'est une différence de langue, un byte = un octet mais Gb = gigabit en français !
Pour le stockage, il est généralement utilisé GB ou Go, mais pour des débits, il est souvent utilisé Gb !
Exemple : 512 kb/s qui représente 512/8 = 64 ko/s
Voilà, après pour tes DVD 4.7 GB = 4.7 Go et pour les minutes tout dépend du format de compression comme te l'a indiqué Beert
Voilà ++

I have a slight problem; I want to burn 4.4GB onto a 4.7GB DVD (an ISO file), and it's telling me that it won't fit.

Hello

It's another problem...

Disk manufacturers count in decimal bytes > 1Go/GB = 1000Mo/MB = 1000000ko/kB = 1000000000bytes/Bytes

Windows counts in binary bytes > 1Gio/GiB = 1024Mio/MiB (2^10) = 1048576kio/kiB (2^20) = 1073741824bytes/Bytes (2^30) but uses the prefixes of the decimal system, which mainly serves to mislead everyone.

A 4.7Go/GB (in decimal) DVD = 4.36Gio/GiB (in binary)

So Tera = 10^12; Giga = 10^9; Mega = 10^6; kilo = 10^3 regardless of the unit of measurement, grams, bytes, meters, etc., etc...

And Tebi = 2^40; Gibi = 2^30; Mebi = 2^20; kibi = 2^10

Hello,
I'm not sure about it, but I've always been told that it was used for the buffer. Need to check.

And an Englishman or American will tell you that we should no longer measure distances in meters but in inches, miles, etc. It's the same for liters and gallons. Why should they change and not us... Of course, the decimal system is much easier but that's another debate ^^

By the way, it's not bit or octet but byte or octet... 8 bits = 1 octet = 1 byte.

Gb = gigabit and GB = gigabyte.

Maybe, but ANSI is the American reference measure:

ANSI: American National Standards Institute (ANSI)
the meter is defined by the International System (SI)

ANSI or SI or even ISO, it doesn't change the fact that the Americans won't give up their measurement system. ^^

Gb = gigabit / Go = gigabyte... 1 byte = 8 bits...

So the difference is not 5% since there are 8 times more bits in a GB than in 1 Gb...

Instead of spreading your "knowledge," learn to write the abbreviations correctly: GB for gigabyte, B = byte, b = bit

And since a byte = 1 octet, there is no 5% difference, no, 4.7GB = 4.7Go because contrary to what you claim, in 1 kilobyte there are 1000 bytes and not 1024, 1024 is for a kibibyte.

kilo = 10^3 and kibi = 2^10... So respectively 1000 for kilo and 1024 for kibi.

ah the idiot! on top of that it's a 2.3% difference according to your moron's theory... why do such dumb people come to give advice?!

Ah yes, I almost forgot => octet (Wikipedia is also your friend!)

It's very often that many questions would find an answer BEFORE being asked again for the umpteenth time if some took the time to search on Google or even on the forum.

The topic dates back to February 27, 2005, and the answer has been there since February 27, 2005... I'm not the one who dug up this thread...
