About converting Megabytes to Bytes
Megabytes (MB) and Bytes (B) are both units of digital storage, so converting between them is a single multiplication: multiply your Megabytes figure by 1,000,000. Ten Megabytes comes to 10,000,000 Bytes, and a hundred works out at 100,000,000 Bytes.
Rule of thumb: going from Megabytes to Bytes multiplies, so the figure always grows — one Megabyte is already 1,000,000 Bytes. If your answer came out smaller, you have the conversion the wrong way round.
What is a Megabyte?
A megabyte is a million bytes under the SI prefixes this site uses, though Windows will call 1,048,576 bytes a megabyte; the IEC name for that binary version is the mebibyte (MiB). The best illustration of how confused this all got is the 1.44 MB floppy disk, whose "MB" was neither one nor the other — it meant 1,024,000 bytes, a decimal thousand of binary kilobytes, and essentially nothing else has ever used that unit. Today the megabyte is the natural size of a photo, a song or a document.
What is a Byte?
The byte is the unit computers actually store things in, and it has not always been eight bits. Werner Buchholz coined the word at IBM in 1956, when a byte meant however many bits a particular machine needed to hold one character — six, seven and nine-bit bytes all existed. Eight bits became the standard with the IBM System/360, and the industry never looked back. Because that old ambiguity was real, networking standards still say "octet" when they want to be unmistakable about meaning exactly eight bits.
To put both in perspective: a minute of MP3 audio is roughly a megabyte, while a byte holds a single letter of plain text.

Frequently asked questions
How many Bytes are in one Megabyte?
There are 1,000,000 Bytes in one Megabyte.
How do I convert Megabytes to Bytes?
Multiply the number of Megabytes by 1,000,000. For example, 10 Megabytes = 10,000,000 Bytes.
What is 100 Megabytes in Bytes?
100 Megabytes is equal to 100,000,000 Bytes.
How do I convert Bytes to Megabytes?
Multiply the Bytes value by 0.000001 (or divide by 1,000,000).
Is this Megabytes to Bytes conversion exact?
Yes, exactly. Both units are fixed against the same base by definition, and 1 Megabyte = 1,000,000 Bytes is the complete value — nothing is rounded away.
