Is a KB 1000 B or 1024 B?

A kilobyte is a multiple of the unit byte of digital information. The International System of Units (SI) depicts the prefix kilo as 1000 (103). So in Decimal SI (base 10), 1 Kilobyte is equivalent to 1000 bytes.

On the other hand in Binary (base 2) system, 1 Kilobyte is equal to 1024 bytes. The unit symbol of Kilobyte is KB. A Kilobyte is actually equal to 210 bytes, which makes it equivalent to 1024 bytes in practical information technology. And The Microsoft operating system uses this convention. 

Using our tool, you can convert kilobytes to bytes, megabytes, megabytes, and terabytes for base 10 (decimal) and base 2 (binary) systems.

Check out these examples:

1 KB = 1,000 Bytes in Decimal SI (base 10)

1 KB = 1,024 Bytes in Binary (Base 2)

10 KB = 10.000 B in Decimal SI (base 10)

10 KB = 10.240 B in Binary (Base 2)

1 MB = 1,000 KB in Decimal SI (base 10)

1 MB = 1,024 KB in Binary (Base 2)

1 GB = 1,000,000 KB in Decimal SI (base 10)

1 GB = 1,048,576 KB in Binary (Base 2)
