Convert Terabytes to Bytes (TB to B)
1 terabyte (TB) = 1000000000000 bytes (B). 1 B = 1 × 10⁻¹² TB. Example: 15 TB = 15 × 1000000000000 = 15000000000000 B.

How to Convert Terabyte to Byte
- 1 TB = 1000000000000 B
- 1 B = 1 × 10⁻¹² TB
- Example: convert 15 TB to B: 15 TB = 15 × 1000000000000 B = 15000000000000 B
Formula
B = TB × 1000000000000
Derivation from SI units:
- 1 TB = 10¹² bytes = 1000 GB.
- 1 byte = 8 bits (an octet).
- 1 TB = 8000000000000 bit ÷ 8 bit per B = 1000000000000 B
Both units are defined exactly, so the factor is exact. Terabyte definition: terabyte; Byte definition: byte.
Worked examples
- A reading of 4 TB converts to 4000000000000 B.
4 TB × 1000000000000 = 4000000000000 B - A value of 12 TB is 12000000000000 B.
12 TB × 1000000000000 = 12000000000000 B

Where it's used
Terabytes are used for hard drives and SSDs, while bytes appear in file and memory sizes. Both measure amount of digital information, so the conversion is a fixed factor.
