How to convert bytes to megabytes
- Formula:
megabytes = bytes × 0.000001 - Put in the value: 100 bytes.
- Result: 0.0001 megabytes.
Bytes to megabytes table
| bytes | megabytes |
|---|---|
| 1 b | 0.000001 mb |
| 2 b | 0.000002 mb |
| 5 b | 0.000005 mb |
| 10 b | 0.00001 mb |
| 20 b | 0.00002 mb |
| 50 b | 0.00005 mb |
| 100 b | 0.0001 mb |
| 500 b | 0.0005 mb |
| 1,000 b | 0.001 mb |
Converting the other way: megabytes to bytes
bytes = megabytes × 1,000,000. So 0.0001 megabytes is back to 100 bytes; one megabyte is 1,000,000 bytes. See the megabytes to bytes table.
Quick estimate in your head
For a rough answer, multiply by about 0.000001: 100 × 0.000001 ≈ 0.0001 mb, against the exact 0.0001 mb (0.0% out). Good enough to check that a calculated result is sensible.
Common mistakes
The usual slip is using the factor the wrong way round. A byte is smaller than a megabyte, so the number of megabytes must come out smaller than the number of bytes. If your answer goes the other way, divide instead of multiplying.
About the units
Byte (b) and megabyte (mb) are both units of data. One byte equals 0.000001 megabytes, and one megabyte equals 1,000,000 bytes. Results on this page are rounded for display; the conversion itself uses the exact definitions.
Data conversions come up when comparing storage on phones and drives, file and download sizes, and internet plans.

Questions
How many megabytes are in 100 bytes?
0.0001 megabytes.
What is the formula to convert bytes to megabytes?
megabytes = bytes × 0.000001
How many megabytes are in one byte?
One byte is 0.000001 megabytes, so multiply any number of bytes by 0.000001.
Is 100 b more than 100 mb?
No. 100 bytes is 0.0001 megabytes, which is less than 100 megabytes.
How do I convert bytes to megabytes in a spreadsheet?
Put the number of bytes in A1 and type =A1*0.000001 in the next cell. Fill the formula down to convert a whole column.
