Convert Bytes to Megabytes
B to MB · digital storage conversion
What are bytes and megabytes?
A byte is 8 bits, enough to store one character of text. A megabyte is one million bytes, roughly a minute of MP3 audio. 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 bytes to megabytes
1 B = 0.000001 MB. To convert, multiply the number of bytes by 0.000001. For example, 5 B = 0.000005 MB, and 20 B = 0.00002 MB. To go the other way, multiply megabytes by 1,000,000 (since 1 MB = 1,000,000 B).

FAQ
What is 1 B in MB?
1 B = 0.000001 MB. To convert any amount, multiply the number of bytes by 0.000001.
How do I convert megabytes back to bytes?
Go the other way: 1 MB = 1,000,000 B, so multiply megabytes by 1,000,000 to get bytes.
Is a byte bigger than a megabyte?
No — 1 B is the smaller unit, equal to 0.000001 MB (it takes 1,000,000 B to make one MB).
Are these digital storage conversions exact?
They use the standard internationally-defined conversion factors. Results are rounded to six significant figures for readability, which is accurate enough for everyday and most technical use.
