Torrent page says 1.19GB but my torrent is 1.28GB

As in the title. Did I do something wrong?

Here is the link to the torrent I uploaded.

@Richiroma I wonder if it is based on k=1000 vs k=1024
Size: 1.19 GB (1,277,338,107 bytes)
If based on 1024 bytes = 1 kb and so on for mb, gb, tb etc. - (This is the correct way)
1,277,338,107 bytes = 1,247,400.5 KB = 1,218.16 MB = 1.19 GB
Often mistaken as k=1000, then 1,277,338,107 bytes = 1.28 GB
Although valid for other units, For example, 1 km = 1000 m, 1 kg = 1000 g etc. doesn't apply to bytes. For technical reasons, it needs to be power of 2 (2, 4, 8, 16, 32, 64,128, 256, 512, 1024..)

Thanks. Though I have not a clue how or why the math is the way stated, I'm going to assume all is right with my torrent and I can just go about my day.

@Richiroma ...
This is normal, known as size allocation unit ...
Any files requires an extra bytes/size to run and executes its programme/function from the disk properly ...
It relies and depends on what format partition (OS) Operating System ...
[right click on any file/properties/general/detils - size difference from the disk]

ex : 1kb of data

Since we're dealing with the word kilo that is used for international measurement, we'd assume that has a value of 1000. But since in this case we're dealing with digital data that is presented and stored in binary format, we need to base 2 instead of base 10. So instead of 10, 100, 1000 we go gor 2, 4, 8, 16... 1024... 2048, etc.

But it's important to notice that, although the binary is pretty much the standard used for most operating systems and programs, the international system measurement still exists, can be used and most definitely is used arbitrarily, creating this kind of confusion we're dealing with here.

In the digital world the one glaring (and often misleading) exception to the binary rule is storage (disk). Vendors of that tend to use the standard 1000's rather than the 1024's, no doubt because it makes their disk units seem larger... Just something to know when you buy a 1 TB disk that your O/S claims only has ~975 GB of space.

Exactly ...
As I pointed out [from above] ...
Any files requires an extra bytes/size to run and executes its programme/function from the disk properly ...
It relies and depends on what format partition (OS) Operating System ... known as Allocation Unit / Cluster Size ...
[requires disk space/partition to work properly]

ex : 4.37 DVD disc ...
Binary units use multiples of 2 rather than 10. So in binary units (1 KB = 1 kilobytes or 1024 bytes, 1 MB = megabyte or 1048576 bytes, 1GB = gigabyte or 1073741824).
Therefore, stated capacity of a single layer DVD-R is 4.7 GB but in this case it means 4,700,000,000 bytes, which converted to computer GB gives 4.37.

The indication on a DVD5 disk is that it will hold 4.7GB of data.
How much of that space is readily accessible for data that I want to write to the disk?
For example, if I write 4.7GB of data to a DVD5 disk, will all my data be readable and retriable?
There must be room for a Table of Contents (TOC) and other things that the disk may have to have there.

I have noted that when recording a movie on a DVD5 disk, it will not go over about 4.3GB.
This leaves an area of 400MB not written too.

@john32123666 Your statements are true, but this is different than what I was saying. Mine is about inconsistent nomenclature; yours is mostly about allocation overhead on disks and the overhead of various data formats.
