How Many Bytes in a Kilobyte?
Quick Answer
There are 1,000 bytes in a kilobyte (KB) using the SI standard, or 1,024 bytes in a kibibyte (KiB) using the binary standard.
1 KB = 1,000 bytes (SI) or 1 KiB = 1,024 bytes (binary)
Understanding the Conversion
In the SI (decimal) standard, one kilobyte (KB) equals exactly 1,000 bytes. In the binary standard used by operating systems and memory, one kibibyte (KiB) equals 1,024 bytes (2^10). This discrepancy is why a drive marketed as 500 GB appears as about 465 GiB in your computer.
Formula
1 KB = 1,000 bytes (SI) or 1 KiB = 1,024 bytes (binary)
Common Examples
| Description | Value |
|---|---|
| A short text email | About 2-5 KB |
| A small text file | About 1-10 KB |
| A favicon image | About 1-5 KB |

What is the formula to convert kilobyte to bytes?
The formula is: 1 KB = 1,000 bytes (SI) or 1 KiB = 1,024 bytes (binary). To convert, multiply the number of kilobytes by 1,000 to get the equivalent in bytes.
How do I convert bytes to kilobyte?
To convert bytes to kilobyte, divide the number of bytes by 1,000. For example, 5,000 bytes equals 5 kilobytes.
