Processing and privacy: The result is calculated inside your browser and your data is not sent to any server.
How to use it
- Type the value in the kilobytes box.
- Read the result in bits as you type, and pick the precision you need.
- Swap the direction to convert back, or copy the result.
How it is calculated
bit = kB × 8,000
Multiply the value in kilobytes by 8,000 to get bits.
Example
To convert 25 kB to bits: 25 × 8,000 = 200,000 bit.
Conversion table

| 5 | 40,000 |
| 10 | 80,000 |
| 20 | 160,000 |
| 25 | 200,000 |
| 50 | 400,000 |
| 100 | 800,000 |
| 250 | 2,000,000 |
| 500 | 4,000,000 |
| 1,000 | 8,000,000 |
About the units
- Kilobyte
- A decimal (SI prefix) unit equal to exactly 1000 bytes. Not the same as the binary kibibyte, which is 1024 bytes.
- Bit
- The smallest unit of digital information, holding one of two values, 0 or 1. Eight bits make exactly one byte.
Limits and caveats
- Results are rounded for display and computed with the browser's floating point precision (about 15 significant digits).
- Both unit factors are exact by their official definitions.
Questions about this tool
How many bits are in one kilobyte?
1 kB = 8,000 bit exactly.
How do I convert kilobytes to bits?
Use bit = kB × 8,000. For example, 25 kB = 200,000 bit.
How many kilobytes are in one bit?
1 bit = 0.000125 kB.
Why does a 1 TB drive show about 931 GB on my computer?
Drive makers count 1 TB as 10^12 bytes, while Windows divides by 2^30 and labels the result GB even though it is really GiB. So 10^12 ÷ 1,073,741,824 gives about 931.32, and no space is missing.
What is the difference between a kilobyte and a kibibyte?
A kilobyte (kB) is a decimal unit of 1000 bytes and a kibibyte (KiB) is a binary unit of 1024 bytes. The same split applies to mega and mebi, giga and gibi, and the gap grows at each step.
