Bytes to Tebibytes (B to TiB)
1 byte equals 9.094947018×10⁻¹³ tebibytes (rounded).
How to convert bytes to tebibytes
To convert bytes to tebibytes, multiply the number of bytes by 9.094947018×10⁻¹³. The factor is rounded to 10 significant digits. To go the other way, multiply tebibytes by 1,099,511,627,776.
tebibytes = bytes × 9.094947018×10⁻¹³
Example: 10 bytes = 9.094947018×10⁻¹² tebibytes.
Decimal prefixes (kB, MB, GB) are powers of 1,000; binary prefixes (KiB, MiB, GiB) are powers of 1,024. Storage makers use decimal; Windows reports binary but labels it GB.
About these units
Byte (B)
Eight bits. The basic addressable unit of memory and storage.
Werner Buchholz coined the word byte in June 1956 while working on the IBM Stretch computer; the earliest supporting document is dated 11 June 1956. He respelled bite on purpose, in his words to avoid accidental mutation to bit. At that stage a byte was any group of one to six bits, and a move to eight bits was considered in August 1956 and built into the design soon after. Louis Dooley later claimed he had coined the term around 1956 or 1957 on the SAGE project at MIT Lincoln Laboratory, where it meant groups of four bits, but Fred Brooks credited Buchholz.
IBM's System/360 adopted the eight-bit byte, and its success made that size the standard. The symbol is a capital B, and the unambiguous alternative is octet, a word used in protocol standards such as RFC 791. A byte can hold 256 distinct values, enough for a letter of the alphabet in a simple character set, which is why files and memory addresses are counted in bytes.
The byte is the reference unit for digital storage on this site.

Tebibyte (TiB)
Exactly 2⁴⁰ bytes, about 9.9% larger than a terabyte.
At tera scale the two systems drift furthest apart among the common units. The tebibyte equals 2 to the fortieth bytes, or 1,099,511,627,776 bytes, and the IEC created the bi prefixes in 1998 to separate powers of 1,024 from SI powers of 1,000. A power-of-10 terabyte is about 9 percent smaller than a tebibyte, so the gap has more than tripled since the kibibyte, which is only about 2.4 percent larger than a kilobyte.
Practical consequences are visible on any new drive. A 1 TB drive may be reported as about 931 GB by an operating system that counts in binary but labels it GB. Some systems use TB for 1,024 to the fourth bytes, but the JEDEC standard does not mention TB or larger units. The unit is defined in IEC 80000-13, and its TiB symbol is rarely used outside tools such as KDE and Qt-based applications.
1 tebibyte = 1,099,511,627,776 bytes (exactly).
