The byte
A byte is 8 bits — the smallest addressable unit on virtually every modern computer. ASCII text is one byte per character; UTF-8 ranges from 1 to 4 bytes per character.
Bytes to Megabytes Converter
1 B = 1.0000 × 10^−6 MB
1 byte equals 1.0000 × 10^−6 megabytes. To convert bytes to megabytes, multiply the byte value by 1.0000 × 10^−6. For quick reference: 1 B = 1.0000 × 10^−6 MB, 5 B = 5.0000 × 10^−6 MB, 10 B = 1.0000 × 10^−5 MB, 100 B = 0.0001 MB.
Formula
Megabytes = Bytes × 1.0000 × 10^−6Quick

Frequently asked questions
- How many megabytes are in 1 byte?
- 1 byte equals 1.0000 × 10^−6 megabytes.
- How do I convert bytes to megabytes?
- Multiply the byte value by 1.0000 × 10^−6. So x B × 1.0000 × 10^−6 = the equivalent in MB.
- What is 5 bytes in megabytes?
- 5 bytes equals 5.0000 × 10^−6 megabytes.
- What is 10 bytes in megabytes?
- 10 bytes equals 1.0000 × 10^−5 megabytes.
- What is 100 bytes in megabytes?
- 100 bytes equals 0.0001 megabytes.
- How do I convert back from megabytes to bytes?
- Multiply the megabyte value by 1000000. For example, 1 MB = 1000000 B.
- Is the byte bigger than the megabyte?
- No. 1 byte is smaller than 1 megabyte. It takes 1000000 bytes to equal 1 megabyte.
- Are these conversion factors exact?
- Yes. The factor of 1.0000 × 10^−6 is derived directly from the SI definitions of byte and megabyte.
About the byte and the megabyte
The megabyte
The megabyte (MB) equals 1,000,000 bytes (decimal) or 1,048,576 bytes (binary, formally 'mebibyte' MiB — a roughly 5% difference). Used for music files, photographs, and most everyday document sizes.
