Bits to Bytes Converter
Convert bit to byte instantly. 1 bit = 0.125 B, worked steps and a full reference table.
How to use it
- Type the value in bit — the result updates as you type.
- Use Swap to flip the direction, or change either dropdown to convert between any two units.
- Click the result to copy it. The URL updates too, so you can bookmark or share the exact conversion.
Examples
| 1 bit | 0.125 B |
| 5 bit | 0.625 B |
| 10 bit | 1.25 B |
| 100 bit | 12.5 B |
One bit equals 0.125 bytes (B). To convert bits to bytes, multiply by 0.125; to go back the other way, multiply by 8 instead.
The converter above does it as you type and shows the working underneath, so you can check the arithmetic rather than take the number on trust.
What bits and bytes actually measure
Bit (bit) — A bit is one binary digit — a single 0 or 1. Network speeds and the lowest level of all digital storage.
Byte (B) — A byte is eight bits, historically the space for one character of text. File sizes and memory addressing.

| bit | B |
|---|---|
| 1 bit | 0.125 B |
| 2 bit | 0.25 B |
| 5 bit | 0.625 B |

How to convert bits to bytes by hand
Multiply the number of bits by 0.125.
For example, 25 bit × 0.125 = 3.125 B.
Going the other way, divide by 0.125 — or multiply by 8, which is the same thing and easier to do in your head.
Everything runs in your browser
There is no server involved in the calculation. The numbers you type never leave your device, nothing is logged, and the page keeps working with no connection once it has loaded. That is not a marketing line — it is simply how the tool is built, because a calculation like this has no reason to touch a network.
Questions people ask
How many B are in 1 bit?
1 bit equals exactly 0.125 B. Multiply any value in bit by 0.125 to get byte.
Is anything uploaded to a server?
No. The whole calculation happens in your browser. Nothing is sent anywhere, and the page keeps working offline once loaded.
