Convert Megabytes to Bytes
MB to B · digital storage conversion
What are megabytes and bytes?
A megabyte is one million bytes, roughly a minute of MP3 audio. A byte is 8 bits, enough to store one character of text. For scale: a photo is a few MB, an HD movie a few GB, and a modern drive holds 1 TB or more. These use decimal (1 KB = 1,000 bytes).
How to convert megabytes to bytes
1 MB = 1,000,000 B. To convert, multiply the number of megabytes by 1,000,000. For example, 5 MB = 5,000,000 B, and 20 MB = 20,000,000 B. To go the other way, multiply bytes by 0.000001 (since 1 B = 0.000001 MB).

FAQ
What is 1 MB in B?
1 MB = 1,000,000 B. To convert any amount, multiply the number of megabytes by 1,000,000.
How do I convert bytes back to megabytes?
Go the other way: 1 B = 0.000001 MB, so multiply bytes by 0.000001 to get megabytes.
Is a megabyte bigger than a byte?
Yes — 1 MB is the larger unit, equal to 1,000,000 B.
