The main non-SI unit for **computer data storage** is the byte.

1 byte is equal to 1.0E-21 zettabyte, or 0.0009765625 kilobyte.

Note that rounding errors may occur, so always check the results.

The SI prefix "zetta" represents a factor of
10^{21}, or in exponential notation, 1E21.

So 1 zettabyte = 10^{21} bytes.

The definition of a byte is as follows:

A byte is the basic unit of measurement of information storage in computer science. In many computer architectures it is a unit of memory addressing, consisting of 8 bits.

Since computer memory comes in base two rather than 10, a large portion of the software and computer industry use binary estimates of the SI-prefixed quantities, while producers of computer storage devices prefer the SI values. This is why a computer hard drive advertised with a "100 GB" decimal storage capacity actually contains no more than 93 GB of 8-bit (power of 2) addressable storage.

A kilobyte is a unit of information or computer storage equal to 1024 bytes, assuming a binary system. This is not a standard SI definition, which would use kibibyte to represent 1024 bytes. However, most people have requested the more common usage, so the non-SI version is used on this site.
