Convert terabytes to megabytes: 1 TB = 1000000 MB. Exact conversion factor, formula, 18-row table and worked examples, with JSON API and MCP access.
Formula
1 TB = 1000000 MB
megabytes = terabytes × 1000000 — reverse: terabytes = megabytes × 0.000001
The factor is derived from the SI definitions of both units (base unit: B) as listed in NIST SP 811; results on this page are shown to 6 significant figures, the API returns up to 12.
Worked examples
- 1.5 TB = 1500000 MB
- 700 TB = 700000000 MB
- 2048 TB = 2048000000 MB

FAQ
How many megabytes are in one terabyte?
1 TB = 1000000 MB. The factor comes from the SI definitions of both units (NIST SP 811 / BIPM), so it is exact or correct to at least 10 significant figures.
What is the formula to convert terabytes to megabytes?
Multiply the value in terabytes by 1000000: megabytes = terabytes × 1000000. For example, 1.5 TB = 1500000 MB.
How do I convert megabytes back to terabytes?
Multiply by the inverse factor 0.000001 (terabytes = megabytes × 0.000001), or use the megabytes-to-terabytes page.
