Byte to Bit Converter (B to b)
1 byte = 8 bit. A byte is 8 bits.
⇄ Swap
Result
1,024 B = 8,192 b
How to convert byte to bit
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 × 8
Worked example
1,024 B × 8 = 8,192 b
Byte to Bit quick-reference table
| Byte (B) | Bit (b) |
|---|---|
| 1 B | 8 b |
| 2 B | 16 b |
| 4 B | 32 b |
| 8 B | 64 b |
| 16 B | 128 b |
| 1,024 B | 8,192 b |
Real-life examples
A 1,024 byte packet is 8,192 bits, and a 4 byte (32-bit) integer uses 32 bits.
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 byte in bit?
1 byte = 8 bit (B to b).
What is the formula to convert B to b?
b = B × 8. For example, 1,024 B × 8 = 8,192 b.
How do I convert b back to B?
Use the reverse converter: 1 bit = 0.125 byte. Check: 8,192 b converts back to 1,024 B.
