Terabyte

The terabyte is a multiple of the unit byte for digital information. The prefix tera represents the fourth

power of 1000, and means 1012 in the International System of Units (SI), and therefore one terabyte is

one trillion(short scale) bytes. The unit symbol for the terabyte is TB.

1 TB = 1000000000000bytes = 1012bytes = 1000gigabytes.

A related unit, the tebibyte (TiB), using a binary prefix, is the corresponding 4th power of 1024. One

terabyte is about 0.9095 tebibytes, or 931 gibibytes.
