You can do the reverse unit conversion from terabyte to KB, or enter any two units below:

KB to gigabit

KB to bit

KB to gigabyte

KB to kibibyte

KB to mebibit

KB to byte

KB to tebibyte

KB to gibibit

KB to kilobit

KB to gibibyte

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.

A terabyte (commonly abbreviated TB) is a measurement term for data storage capacity.

The number of bytes in a terabyte is sometimes stated to be approximately 1.0995 × 10^{12}. This difference arises from a conflict between the long standing tradition of using binary prefixes and base 2 in the computer world, and the more popular decimal (SI) standard adopted widely both within and outside of the computer industry. Standards organizations such as IEC, IEEE and ISO recommend to use the alternative term tebibyte (TiB) to signify the traditional measure of 1024^{4} bytes, or 1024 gibibytes.

The capacities of computer storage devices are typically advertised using their SI standard values, but the capacities reported by software operating systems uses the binary values. A NTFS formatted terabyte hard drive shows 931 gigabytes of free, usable storage space under Windows XP.

Most users prefer to calculate unit conversions using the binary definition, so this site uses non-SI units.
