About these units
Kilobyte (10^3 bytes) (kB (10^3))
A decimal kilobyte equals 1,000 bytes, reflecting the SI prefix kilo = 10³. Storage device manufacturers standardize on this definition because it scales cleanly and simplifies marketing and specification. This creates a mismatch with binary kilobytes (1,024 bytes) historically used in RAM and file systems. As storage capacities grew, this discrepancy became increasingly noticeable, leading standards bodies to promote explicit binary prefixes (KiB, MiB) for clarity. Despite these efforts, decimal kilobytes remain dominant in contexts such as hard drives, flash memory packaging, and communication standards.
Terabyte (10^12 bytes) (TB (10^12))
A decimal terabyte equals 1 trillion bytes, a unit that defines modern large-capacity storage devices—from consumer HDDs to enterprise backup systems. The distinction between binary (1.099 trillion bytes) and decimal terabytes becomes especially noticeable at this scale. Disk manufacturers universally use decimal TB, while many file systems report binary values unless specifically configured otherwise. Terabytes represent massive datasets, enabling high-resolution video libraries, large backups, and entire scientific databases.
