How it is calculated
kB = KiB × 1.024
Multiply the value in kibibytes by 1.024 to get kilobytes.
Example
To convert 25 KiB to kilobytes: 25 × 1.024 = 25.6 kB.

About the units
- Kibibyte
- A binary (IEC prefix) unit equal to exactly 2^10 = 1024 bytes. Many programs display it as KB.
- Kilobyte
- A decimal (SI prefix) unit equal to exactly 1000 bytes. Not the same as the binary kibibyte, which is 1024 bytes.
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 kilobytes are in one kibibyte?
1 KiB = 1.024 kB exactly.
How do I convert kibibytes to kilobytes?
Use kB = KiB × 1.024. For example, 25 KiB = 25.6 kB.
How many kibibytes are in one kilobyte?
1 kB = 0.976563 KiB.
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.
