In 1 bytes there are 8 bits. Meanwhile in 1 bits there are 0.125 bytes. Keep reading to learn more about each unit of measure and how they are calculated. Or just use the Bits to Bytes calculator above to convert any number.

A bit (b) is the smallest unit of digital data. It can be 0 or 1. A byte (B) is a group of bits used to store and move data in computers.
To convert bytes to bits, use this rule:
Formula:
Examples:
Tip: Watch the case. B means bytes and b means bits.
There are 8 bits in 1 byte. This is the standard used in modern computing and data storage.
A bit is the smallest unit of data, shown as 0 or 1. A byte is a group of 8 bits. Bytes are common for file sizes, while bits are common for data speeds.
To convert bytes to bits, multiply by 8.
Formula: bits = bytes × 8
To convert bits to bytes, divide by 8.
Formula: bytes = bits ÷ 8
Computers use bytes as a practical unit for storing values like letters and small numbers. An 8-bit byte can represent 256 different values (0 to 255), which fits common data needs well.
No. Lowercase b means bit. Uppercase B means byte.
Multiply by 8.
10 bytes × 8 = 80 bits
100 bytes × 8 = 800 bits
1,000 bytes × 8 = 8,000 bits
It depends on how KB is defined.
KB usually means 1,000 bytes. KiB means 1,024 bytes. That small gap grows at larger sizes, so it matters for accurate byte-to-bit conversions.
Network speeds are often shown in bits per second (bps) because early systems measured data as bit streams. File sizes are usually shown in bytes because bytes match how data is stored.
Multiply by 8.
Formula: bps = B/s × 8
Example: 50 bytes/second = 400 bits/second
Divide by 8.
Formula: B/s = bps ÷ 8
Example: 800 bps = 100 bytes/second
No. The data stays the same. Only the unit changes. It’s like converting inches to feet.
Almost all modern systems use 8-bit bytes. Some older or specialized systems used different sizes, but they are rare today. For most byte-to-bit conversions, 1 byte = 8 bits is correct.
The Calculate Box tool to convert bytes to bits uses the open source script Convert.js to convert units of measurement. To use this tool, simply type a bytes value in the box and have it instantly converted to bits.
