Convert Megabytes to Bits
MB to b · digital storage conversion
What are megabytes and bits?
A megabyte is one million bytes, roughly a minute of MP3 audio. A bit is the smallest unit of digital data, a single 0 or 1. 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 bits
1 MB = 8,000,000 b. To convert, multiply the number of megabytes by 8,000,000. For example, 5 MB = 40,000,000 b, and 20 MB = 160,000,000 b. To go the other way, multiply bits by 1.2500e-7 (since 1 b = 1.2500e-7 MB).

FAQ
What is 1 MB in b?
1 MB = 8,000,000 b. To convert any amount, multiply the number of megabytes by 8,000,000.
How do I convert bits back to megabytes?
Go the other way: 1 b = 1.2500e-7 MB, so multiply bits by 1.2500e-7 to get megabytes.
Is a megabyte bigger than a bit?
Yes — 1 MB is the larger unit, equal to 8,000,000 b.
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.
