How to convert bytes to megabytes
Worked example: convert 250 bytes to megabytes. Using megabytes ← bytes ÷ 1,000,000, we get 250 × 0.000001 = 0.00025 MB. To check the result, convert back: 0.00025 MB ÷ 0.000001 = 250 B.

About the byte and the megabyte
A byte is 8 bits and the basic unit of digital storage; one plain English character takes one byte. File sizes below 1 KB are shown in bytes.
A megabyte is 1,000,000 bytes in decimal. A typical smartphone photo is a few megabytes and an MP3 song around 3 to 5 MB. In binary terms 1 MiB is 1,048,576 bytes.
One megabyte equals 1,000,000 bytes, which makes the megabyte the larger unit of the two.
Everyday sizes in bytes and megabytes
| Everyday example (approximate) | In bytes | In megabytes |
|---|---|---|
| A short text message | 140 B | 0.00014 MB |
| A plain-text email | 5,000 B | 0.005 MB |
| A web page | 2,000,000 B | 2 MB |
| A phone photo | 3,000,000 B | 3 MB |
| A 3-minute MP3 song | 5,000,000 B | 5 MB |
| A 2-hour HD movie | 3,000,000,000 B | 3,000 MB |
Bytes to megabytes FAQ
How many megabytes are in one byte?
One byte equals exactly 0.000001 megabytes. In the other direction, one megabyte equals 1,000,000 bytes.
How do I convert bytes to megabytes without a calculator?
convert 250 bytes to megabytes. Using megabytes ← bytes ÷ 1,000,000, we get 250 × 0.000001 = 0.00025 MB. To check the result, convert back: 0.00025 MB ÷ 0.000001 = 250 B. For a quick estimate, round the factor to 0.000001. Then 250 B is about 0.00025 MB, compared with the exact 0.00025 MB (an error of 0%). That is close enough for planning, but use the calculator above when the number matters.
What is a plain-text email in megabytes?
A plain-text email is about 5,000 bytes, which is 0.005 megabytes. Treat that as an approximate everyday figure rather than an official measurement.
Are the bytes and megabytes the same in every country?
A byte is 8 bits everywhere. Decimal MB = 1,000,000 bytes; binary MiB = 1,048,576 bytes.
