How to convert bytes to bits
Bytes and Bits both measure data, so converting is a single multiplication. One B equals 8 bit, so you multiply your bytes value by 8.
Formula: bits = bytes × 8. For example, 10 B = 80 bit.
Bytes to Bits conversion table
| Bytes (B) | Bits (bit) |
|---|---|
| 1 | 8 |
| 2 | 16 |
| 5 | 40 |
| 10 | 80 |
| 25 | 200 |
| 50 | 400 |
| 100 | 800 |
| 1,000 | 8,000 |
Bytes and Bits explained
Bytes (B): Eight bits, the basic unit for file sizes.
Bits (bit): The smallest unit of digital information, one-eighth of a byte.
When you'd convert bytes to bits
You'll convert bytes to bits whenever a measurement is given in one unit but you need it in the other — comparing bytes and bits figures across regions, following a recipe or spec, or double-checking a number. Because 1 B is exactly 8 bit, the result is precise every time.
Frequently asked questions
How many bits are in a byte?
One B equals 8 bit. Multiply your bytes figure by 8 to get bits.
What is the formula to convert bytes to bits?
bits = bytes × 8. The factor 8 is exact.
What is 2 bytes in bits?
2 B = 16 bit. You can enter any value in the converter above to get an instant result.
Is this Bytes to Bits converter accurate?
Yes. It uses the standard conversion factor (1 B = 8 bit) defined by IEC 80000-13 — units of information (bit, byte), so results are exact to several decimal places.
