Convert Bits to Bytes
b to B · digital storage conversion
What are bits and bytes?
A bit is the smallest unit of digital data, a single 0 or 1. 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 bits to bytes
1 b = 0.125 B. To convert, multiply the number of bits by 0.125. For example, 5 b = 0.625 B, and 20 b = 2.5 B. To go the other way, multiply bytes by 8 (since 1 B = 8 b).

FAQ
What is 1 b in B?
1 b = 0.125 B. To convert any amount, multiply the number of bits by 0.125.
How do I convert bytes back to bits?
Go the other way: 1 B = 8 b, so multiply bytes by 8 to get bits.
Is a bit bigger than a byte?
No — 1 b is the smaller unit, equal to 0.125 B (it takes 8 b to make one 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.
