Convert Bits to Megabytes
b to MB · digital storage conversion
What are bits and megabytes?
A bit is the smallest unit of digital data, a single 0 or 1. 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 bits to megabytes
1 b = 1.2500e-7 MB. To convert, multiply the number of bits by 1.2500e-7. For example, 5 b = 6.2500e-7 MB, and 20 b = 0.0000025 MB. To go the other way, multiply megabytes by 8,000,000 (since 1 MB = 8,000,000 b).

FAQ
What is 1 b in MB?
1 b = 1.2500e-7 MB. To convert any amount, multiply the number of bits by 1.2500e-7.
How do I convert megabytes back to bits?
Go the other way: 1 MB = 8,000,000 b, so multiply megabytes by 8,000,000 to get bits.
Is a bit bigger than a megabyte?
No — 1 b is the smaller unit, equal to 1.2500e-7 MB (it takes 8,000,000 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.
