Bit to Byte Converter (b to B)
1 bit = 0.125 byte. A byte is 8 bits.
⇄ Swap
Result
64 b = 8 B
How to convert bit to byte
A byte is 8 bits. Network speeds are quoted in bits per second, but file sizes and memory in bytes, so this ratio of 8 explains why a 100 Mbps connection downloads at 12.5 MB per second at most.
Formula
B = b × 0.125
Worked example
64 b × 0.125 = 8 B
Bit to Byte quick-reference table
| Bit (b) | Byte (B) |
|---|---|
| 8 b | 1 B |
| 16 b | 2 B |
| 32 b | 4 B |
| 64 b | 8 B |
| 128 b | 16 B |
| 256 b | 32 B |
Real-life examples
64 bits is 8 bytes, the size of a 64-bit address, and 256 bits is 32 bytes, the size of an AES-256 key.
Frequently asked questions
How many bits are in a byte?
A byte is 8 bits.
Is Mbps the same as MBps?
No. Mbps is megabits per second and MBps is megabytes per second; one MBps is 8 Mbps.
What is 1 bit in byte?
1 bit = 0.125 byte (b to B).
What is the formula to convert b to B?
B = b × 0.125. For example, 64 b × 0.125 = 8 B.
How do I convert B back to b?
Use the reverse converter: 1 byte = 8 bit. Check: 8 B converts back to 64 b.
Reverse conversion
Need the other direction? Byte to Bit converter (B to b): 1 byte = 8 bit.
