## Conversions

I dont know if this is in the right forum, sorry if its not.

Is 1 million (1 000 000) megabytes 1 terabyte or not.

If not can you correct me please.

No. One Terabyte is 2^40, 1000 Gigabytes, or 1,099,511,627,776 Bytes

I made a recent post here with exact numbers:

http://www.xmboard.com/viewtopic.php?t=42

The values kilobyte, megabyte, gigabyte, etc, are basically multiples of 2^10 since they're based on the binary number system or Base2.

I'm sorry, I just re-read your question and realized I read it wrong. You are almost correct.

1 Terabyte is 1,048,576 Megabytes.

Sizes are not in multiples of 10 or 1000, they're in multiples of 2^10, or 1024.

Yes, 1 000 000 Mb is 1 terabyte(or 0.953674 to be exact)

Isn't it multiplications of 1024?

1024 bytes in a kilobyte
1024 kilobytes in a megabyte
1024 megabytes in a gigabytes
1024 gigabytes in a terabyte

Yes, 1024 is 2^10. I was editing my post as you replied I completely butchered my posts and could only edit one. I hate the 15 minute time limit, I find it pointless.

Perhaps it's good for some things to remain "on the record" if you know what I mean...

Actually you can also define 1 MB as 1.000.000 bytes. 1&1 does this in their terms and as you know harddrive companies specify the size in GB while 1 GB is 1000000000 Bytes. But that 2.4% difference is not important anyway !

Of course it is important!
Its also unfair!
I have a 250gb drive.. i lost 6gb on it
80gb drive - 1.92 gb
20gb drive - .48 gb
so thats.. 8.4 gb lost.
Terrible...

You lost space from file system allocation, not from incorrect conversions. This is normal.

No, i lost space from incorrect conversions.
When i buy a 250 gb drive.. its not really..
250 * 1024 * 1024 * 1024 bytes
its 250 * 1000 * 1000 * 1000 bytes

Just looked at a Maxtor instruction book I had around and they use 1000 for everything rather then 1024.

All companies..
Maxtor, Seagate, Western Digital.

It might not matter for a 100gb drive..
but on a terabyte of storage.. it makes a difference.

Yes, all HD companies use 1000MB = 1GB ... There was a class action lawsuit about this not too long ago ... For misrepresentation of hard drive space.
