Convert Bytes to bits
1 byte = 8 bits · b = B × 8
When you need this conversion
This conversion goes from bytes, the base unit of digital file size, to bits, the unit for network speeds and data rates. Both measure the same physical quantity, so the conversion is exact — the difference is which unit your source, tool, or region happens to use.
Bytes to bits conversion table
| Bytes (B) | Bits (b) |
|---|---|
| 1 B | 8 b |
| 2 B | 16 b |
| 3 B | 24 b |
| 5 B | 40 b |
| 10 B | 80 b |
| 15 B | 120 b |
| 20 B | 160 b |
| 25 B | 200 b |
| 50 B | 400 b |
| 75 B | 600 b |
| 100 B | 800 b |
| 250 B | 2,000 b |
| 500 B | 4,000 b |
| 1,000 B | 8,000 b |
The formula
b = B × 8Because both units measure data, the conversion is a single multiplication by a fixed factor. That factor never changes, so the result is exact.

Frequently asked questions
- How many bits are in a byte?
- There are 8 bits in 1 byte. The formula is b = B × 8.
- How do you convert bytes to bits?
- Use the formula b = B × 8. For example, 10 bytes equals 80 bits.
- Is the bytes to bits conversion exact?
- Yes. Bytes and bits are both units of data, related by an exact defined factor. Displayed results are rounded for readability.
- What is B short for?
- B is the standard symbol for byte. b is the symbol for bit.
