Convert Bytes to Megabytes (B to MB)
1 byte (B) = 0.000001 megabytes (MB). 1 MB = 1000000 B. Example: 15 B = 15 × 0.000001 = 0.000015 MB.

How to Convert Byte to Megabyte
- 1 B = 0.000001 MB
- 1 MB = 1000000 B
- Example: convert 15 B to MB: 15 B = 15 × 0.000001 MB = 0.000015 MB
Formula
MB = B ÷ 1000000
Derivation from SI units:
- 1 byte = 8 bits (an octet).
- 1 MB = 10⁶ bytes = 8 × 10⁶ bits (decimal, SI).
- 1 B = 8 bit ÷ 8000000 bit per MB = 0.000001 MB
Both units are defined exactly, so the factor is exact. Byte definition: byte; Megabyte definition: megabyte.
Worked examples
- A reading of 512 B converts to 0.000512 MB.
512 B × 0.000001 = 0.000512 MB - A value of 4096 B is 0.004096 MB.
4096 B × 0.000001 = 0.004096 MB

Where it's used
Bytes are used for file and memory sizes, while megabytes appear in photos, documents and songs. Both measure amount of digital information, so the conversion is a fixed factor.

Frequently asked questions
How many megabytes are in 1 byte?
1 B = 0.000001 MB.
How do I convert bytes to megabytes?
Multiply the value in B by 0.000001, or divide it by 1000000. For example, 15 B × 0.000001 = 0.000015 MB.
Is the B to MB conversion exact?
Yes. Both units are defined exactly, and 1 B is exactly 0.000001 MB.
