Converting bits to bytes

One byte is made of 8 bits. This tool divides a bit count by 8 to report the equivalent number of bytes — the unit most people use when talking about file sizes.

Worked example

A text file described as 1,600 bits in a low-level network log holds 200 bytes (1,600 ÷ 8). That matches roughly 200 characters of ASCII text, since each ASCII character occupies one byte.

When it is useful

Converting bandwidth figures (measured in bits per second) into file-size units.
Reading protocol and serial-communication logs that count bits.
Explaining to a non-technical audience why an 8 Mbps connection downloads at about 1 MB/s.

A precision note

Keep units separate: lowercase b means bits, uppercase B means bytes. Mixing them is a common source of errors in networking and storage math.

Frequently asked questions

How many bits in a byte? Eight bits, by the standard definition used by this tool.

Why is my internet speed lower than advertised? ISPs advertise in bits per second, but file downloads are measured in bytes per second — a factor of 8 difference before any network overhead.
