How do I convert terabytes back to bytes?

Use the reverse converter: 1 terabyte equals 1e+12 B.

Is this converter accurate?

Yes. It uses the exact SI/NIST definitions of each unit and shows up to 6 significant digits.

Bytes to Terabytes Converter (B to TB)

Formula

To convert bytes to terabytes, multiply the value by 1e-12.

TB = B × 1e-12

Example calculation

Convert 10 B to TB:

10 B × 1e-12 = 1e-11 TB

Decimal vs binary: KB, MB and GB use powers of 1,000 (SI), while KiB, MiB and GiB use powers of 1,024. Storage makers use decimal units; many operating systems and memory sizes use binary ones, which is why a "500 GB" drive shows less space.

About the units

Byte (B): Eight bits, the basic unit of computer storage and the size of one character in many encodings.
Terabyte (TB): 10^12 bytes in the decimal system, used for hard drives and SSDs.
