According to the SI standard and current usage, a terabyte contains 1 trillion bytes.

There is a debate here. For starters, a Kilobyte is either 1000 Bytes or, more accurately, 1024 Bytes. (two to the eight power, 2 X 2 X 2 X 2 X 2 X 2 X 2 X 2). A Megabyte is either a Million Bytes, or digitally, 2 to the 10th or 1,048,576 Bytes. And a Gigbyte is 2 to the 30th. (1,073,741,824). So without totally nerding out, the question is do we count RAM/HD storage digitally or approximately? Since a Byte itself is 8 bits, a digital unit, I vote for counting by powers of 2. OTOH, I think in terms of the approximations.

Well I will answer the same way I do for every other conversion question.

Google it

Google has a great converter that will do almost any conversions.

You gotta click the link and find out for yourself. :D

its a trillion. You don’t have to google it thats why we are here.

It’s not a trillion and it’s not why I’m here. Google does all kinds of conversions, that’s one of it’s many functions

@ perchik its pretty close. Unless you want to type out all 13 digits. I am sure he is just looking for a ball park number. Like a megabyte is not exactly 1000 bytes but in quick figures it figures out as such…..and by the way why are you here?

This is actually just a difference between the SI standard, which defines a terabyte as 10^12 bytes and binary arithmetic, which defines it as 2^40 bytes. To avoid confusion, the latter value is now know as a tebibyte (TiB).

Google performs this calculation correctly.

Now that’s arcane! And very interesting.
