Bits to Bytes Converter
Convert bits to bytes — eight bits to the byte. Results update as you type; exact factors shown.
One bit is 0.125 bytes — see the exact factor, not a rounded rule of thumb.
How the bits to bytes converter works
Storage converts through the byte (8 bits). Drive makers and network speeds use decimal prefixes (1 GB = 10⁹ bytes); operating systems often report binary units (1 GiB = 2³⁰ = 1,073,741,824 bytes) — sometimes labelled "GB". The gap is 7.4% at the gigabyte and 10% at the terabyte.
Australia is fully metric under the National Measurement Act 1960; imperial units appear only in trade with the US and in older documents.

FAQFrequently asked questions about data conversion
How many bits in a byte?
Eight.
Why does my internet speed look eight times faster than my download?
Because connection speed is quoted in megabits and file sizes in megabytes. A 100 Mbps line downloads at about 12.5 MB/s.
What is the difference between Mb and MB?
A lowercase b is bits, an uppercase B is bytes. The factor of eight between them causes constant confusion.
How many bytes is a 1 Gbps connection per second?
125 MB.
Was a byte always eight bits?
No — early machines used six or nine, but eight has been standard since the 1960s.
