Byte to BitConverter
Instantly convert Byte (B) to Bit (bit). Free, accurate, and easy to use.
How to Convert Byte to Bit
To convert Byte (B) to Bit (bit), multiply your value by 8.
Example: 5 B × 8 = 40 bit
What is a Byte?
The byte is the standard unit of digital storage, equal to 8 bits and capable of encoding 256 distinct values (2⁸). It became the norm with IBM's System/360 in 1964 as the smallest addressable memory unit and remains so in virtually all modern computing architectures. File sizes, RAM, and storage capacities are all measured in bytes or multiples thereof. A single ASCII character requires exactly one byte.
What is a Bit?
The bit is the fundamental unit of digital information, representing a single binary value: 0 or 1. The word is a portmanteau of 'binary digit,' coined by statistician John Tukey and popularized by Claude Shannon in his 1948 paper on information theory. Network connection speeds are expressed in bits per second (bps, Kbps, Mbps, Gbps). Eight bits constitute one byte, the standard addressable unit of computer memory.

Frequently Asked Questions
How do I convert Byte to Bit?
Multiply the Byte value by 8. Formula: bit = B × 8. Example: 10 B = 80 bit.
How many Bit are in one Byte?
One Byte (B) equals 8 Bit (bit).
How many Byte are in one Bit?
One Bit (bit) equals 0.125 Byte (B).
What is the exact conversion factor from Byte to Bit?
The conversion factor is 8. Multiply any B value by this number to get bit. For the reverse, multiply by 0.125.
How do I convert Bit back to Byte?
Divide by 8, or equivalently multiply by 0.125. Formula: B = bit ÷ 8.
Is the Byte-to-Bit conversion internationally standardized?
Yes. Both units are defined by international standards (SI or the international yard/pound agreement), so the conversion factor 8 is exact and universally agreed upon.
