Convert Terabytes to Bytes

1 terabyte is 1,000,000,000,000 B. One terabyte is exactly 1000000000000 bytes.

One terabyte is 1000000000000 bytes. To convert terabytes to bytes, multiply by 1000000000000; to go the other way, divide by 1000000000000 or multiply by 1.0000 × 10^-12. The factor is exact rather than rounded: it follows from IEC 80000-13. Exactly one trillion bytes, or 1,000 gigabytes.

Factors are entered by hand from IEC 80000-13 rather than derived from a units library, so the ones that terminate are exact rather than rounded.

How do you convert terabytes to bytes?

  1. 1.Take the measurement in terabytes.
  2. 2.Multiply by 1000000000000 — that is how many bytes fit in one terabyte.
  3. 3.To go back the other way, divide by 1000000000000, or multiply by 1.0000 × 10^-12.
