The terabyte
The terabyte (TB) equals 10¹² bytes. Standard for hard-drive capacity. A 4K movie at typical streaming bitrate uses about 7 GB per hour, so 1 TB holds roughly 140 hours.

- How do I convert back from kilobytes to terabytes?
- Multiply the kilobyte value by 1.0000 × 10^−9. For example, 1 kB = 1.0000 × 10^−9 TB.
- Is the terabyte bigger than the kilobyte?
- Yes. 1 terabyte is larger than 1 kilobyte — specifically 1000000000 times larger.
- Are these conversion factors exact?
- Yes. The factor of 1000000000 is derived directly from the SI definitions of terabyte and kilobyte.
About the terabyte and the kilobyte
The kilobyte
The kilobyte (kB) equals exactly 1,000 bytes in the SI/IEC decimal convention. Most modern OS file managers and storage-vendor marketing use this definition. Older operating systems (Windows up to Vista) used 1 kB = 1,024 B — that value is now strictly called the kibibyte (KiB).
