Convert Byte to Bit
1 byte = 8 bit (bit). For example, 10 byte = 80 bit and 100 byte = 800 bit. Type any value below to convert byte to bit both ways — it runs entirely in your browser.
Try:
Byte to Bit conversion formula
To convert byte to bit, multiply by 8:
bit = byte × 8
Going the other way, 1 bit = 0.125 byte, so
byte = bit × 0.125.

Byte ↔ Bit reference table
| Byte → Bit | Bit → Byte |
|---|---|
| 1 B = 8 bit | 1 bit = 0.125 B |
| 2 B = 16 bit | 2 bit = 0.25 B |
| 5 B = 40 bit | 5 bit = 0.625 B |
| 10 B = 80 bit | 10 bit = 1.25 B |
| 20 B = 160 bit | 20 bit = 2.5 B |
| 50 B = 400 bit | 50 bit = 6.25 B |
| 100 B = 800 bit | 100 bit = 12.5 B |
| 250 B = 2,000 bit | 250 bit = 31.25 B |
| 500 B = 4,000 bit | 500 bit = 62.5 B |
| 1000 B = 8,000 bit | 1000 bit = 125 B |
About byte and bit
Byte: A byte is 8 bits — the basic addressable unit of computer storage.
Bit: A bit is a single binary digit (0 or 1). 8 bits = 1 byte.
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 bit are in 1 byte?
- 1 byte = 8 bit (bit).
- How do I convert byte to bit?
- Multiply the number of byte by 8. For example, 10 byte = 10 × 8 = 80 bit.
- How many byte are in 1 bit?
- 1 bit = 0.125 byte.
- Which is bigger, byte or bit?
- 1 byte equals 8 bit, so a byte is the larger unit.
