Convert Terabytes to Megabytes

1 terabyte is 1,000,000 MB. One terabyte is exactly 1000000 megabytes.

One terabyte is 1000000 megabytes. To convert terabytes to megabytes, multiply by 1000000; to go the other way, divide by 1000000 or multiply by 1.0000 × 10^-6. The factor is exact rather than rounded: it follows from IEC 80000-13. Exactly one trillion bytes, or 1,000 gigabytes.

How do you convert terabytes to megabytes?

  1. 1.Take the measurement in terabytes.
  2. 2.Multiply by 1000000 — that is how many megabytes fit in one terabyte.
  3. 3.To go back the other way, divide by 1000000, or multiply by 1.0000 × 10^-6.
