Bits & Bytes Converter
Convert between bits, bytes, and their decimal multiples.
Bits, bytes, and the factor of eight
Confusing bits with bytes is a classic mistake, and it matters: a 100 megabit connection delivers about 12.5 megabytes per second, not 100. This converter keeps the eight-to-one ratio and the decimal multiples straight.
Pick a value and its unit, choose the target unit, and it converts through a common base of bits. Lowercase b is bits and uppercase B is bytes, following the usual convention.
