How to convert Byte to Bit
To convert Bytes to Bits, multiply the value by 8.
- Take your measurement in Bytes.
- Multiply it by 8 — the number of Bits in one Byte.
- The result is the same amount, expressed in Bits.
To go the other way, multiply Bits by 0.125 — or simply divide by 8.
For example, a single character of text is about 1 B, which is 8 bit.
About Byte and Bit
A byte is 8 bits, the basic building block for file sizes. It is the foundation for kilobytes, megabytes and gigabytes.
A bit is the smallest unit of digital information — a single 0 or 1. Network and connection speeds are usually quoted in bits per second.
Both the Byte and the Bit are digital units, so converting between them is just a change of scale: one Byte equals 8 Bits, and the Byte is the larger unit.
