How to convert megabytes to bytes
- Formula:
bytes = megabytes × 1,000,000 - Put in the value: 12 megabytes.
- Result: 12,000,000 bytes.
Megabytes to bytes table
| megabytes | bytes |
|---|---|
| 1 mb | 1,000,000 b |
| 2 mb | 2,000,000 b |
| 5 mb | 5,000,000 b |
| 10 mb | 10,000,000 b |
| 12 mb | 12,000,000 b |
| 20 mb | 20,000,000 b |
| 50 mb | 50,000,000 b |
| 100 mb | 100,000,000 b |
| 500 mb | 500,000,000 b |
| 1,000 mb | 1,000,000,000 b |
Converting the other way: bytes to megabytes
megabytes = bytes × 0.000001. So 12,000,000 bytes is back to 12 megabytes; one byte is 0.000001 megabytes. See the bytes to megabytes table.
Quick estimate in your head
For a rough answer, multiply by about 1000000: 12 × 1000000 ≈ 12,000,000 b, against the exact 12,000,000 b (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 megabyte is bigger than a byte, so the number of bytes must come out larger than the number of megabytes. If your answer goes the other way, divide instead of multiplying.
About the units
Megabyte (mb) and byte (b) are both units of data. One megabyte equals 1,000,000 bytes, and one byte equals 0.000001 megabytes. 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 bytes are in 12 megabytes?
12,000,000 bytes.
What is the formula to convert megabytes to bytes?
bytes = megabytes × 1,000,000
How many bytes are in one megabyte?
One megabyte is 1,000,000 bytes, so multiply any number of megabytes by 1,000,000.
Is 12 mb more than 12 b?
Yes. 12 megabytes is 12,000,000 bytes, which is more than 12 bytes.
How do I convert megabytes to bytes in a spreadsheet?
Put the number of megabytes in A1 and type =A1*1000000 in the next cell. Fill the formula down to convert a whole column.
