Bytes to Megabytes (B to MB)
Convert bytes to megabytes: 1 B = 0.000001 MB. Exact conversion factor, formula, 18-row table and worked examples, with JSON API and MCP access.
Formula
1 B = 0.000001 MB
megabytes = bytes × 0.000001 — reverse: bytes = megabytes × 1000000
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 B = 0.0000015 MB
- 700 B = 0.0007 MB
- 2048 B = 0.002048 MB

FAQ
How many megabytes are in one byte?
1 B = 0.000001 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 bytes to megabytes?
Multiply the value in bytes by 0.000001: megabytes = bytes × 0.000001. For example, 1.5 B = 0.0000015 MB.
How do I convert megabytes back to bytes?
Multiply by the inverse factor 1000000 (bytes = megabytes × 1000000), or use the megabytes-to-bytes page.
