How to convert bits to bytes
Bits and Bytes both measure data, so converting is a single multiplication. One bit equals 0.125 B, so you multiply your bits value by 0.125.
Formula: bytes = bits × 0.125. For example, 10 bit = 1.25 B.
Bits to Bytes conversion table
| Bits (bit) | Bytes (B) |
|---|---|
| 1 | 0.125 |
| 2 | 0.25 |
| 5 | 0.625 |
| 10 | 1.25 |
| 25 | 3.125 |
| 50 | 6.25 |
| 100 | 12.5 |
| 1,000 | 125 |
Bits and Bytes explained
Bits (bit): The smallest unit of digital information, one-eighth of a byte.
Bytes (B): Eight bits, the basic unit for file sizes.
When you'd convert bits to bytes
You'll convert bits to bytes whenever a measurement is given in one unit but you need it in the other — comparing bits and bytes figures across regions, following a recipe or spec, or double-checking a number. Because 1 bit is exactly 0.125 B, the result is precise every time.
Frequently asked questions
How many bytes are in a bit?
One bit equals 0.125 B. Multiply your bits figure by 0.125 to get bytes.
What is the formula to convert bits to bytes?
bytes = bits × 0.125. The factor 0.125 is exact.
What is 2 bits in bytes?
2 bit = 0.25 B. You can enter any value in the converter above to get an instant result.
Is this Bits to Bytes converter accurate?
Yes. It uses the standard conversion factor (1 bit = 0.125 B) defined by IEC 80000-13 — units of information (bit, byte), so results are exact to several decimal places.
