Convert Bit to Byte
1 bit = 0.125 byte (B). For example, 10 bit = 1.25 byte and 100 bit = 12.5 byte. Type any value below to convert bit to byte both ways — it runs entirely in your browser.

Bit to Byte conversion formula
To convert bit to byte, multiply by 0.125:
byte = bit × 0.125
Going the other way, 1 byte = 8 bit, so
bit = byte × 8.

Bit ↔ Byte reference table
| Bit → Byte | Byte → Bit |
|---|---|
| 1 bit = 0.125 B | 1 B = 8 bit |
| 2 bit = 0.25 B | 2 B = 16 bit |
| 5 bit = 0.625 B | 5 B = 40 bit |
| 10 bit = 1.25 B | 10 B = 80 bit |
| 20 bit = 2.5 B | 20 B = 160 bit |
| 50 bit = 6.25 B | 50 B = 400 bit |
| 100 bit = 12.5 B | 100 B = 800 bit |
| 250 bit = 31.25 B | 250 B = 2,000 bit |
| 500 bit = 62.5 B | 500 B = 4,000 bit |
| 1000 bit = 125 B | 1000 B = 8,000 bit |
About bit and byte
Bit: A bit is a single binary digit (0 or 1). 8 bits = 1 byte.
Byte: A byte is 8 bits — the basic addressable unit of computer storage.
This converter uses the decimal (SI) convention for KB/MB/GB/TB (1 KB = 1,000 bytes), as used by storage manufacturers and networks. The binary units — KiB, MiB, GiB (1 KiB = 1,024 bytes) — are listed separately, because operating systems often label binary sizes with the decimal names.
Frequently asked questions
- How many byte are in 1 bit?
- 1 bit = 0.125 byte (B).
- How do I convert bit to byte?
- Multiply the number of bit by 0.125. For example, 10 bit = 10 × 0.125 = 1.25 byte.
- How many bit are in 1 byte?
- 1 byte = 8 bit.
- Which is bigger, bit or byte?
- 1 byte equals 8 bit, so a byte is the larger unit.
