Kilobyte

According to the International System of Units (SI), kilo prefix is specified as 1000 (103). Based on this, 1 kilobyte is equal to 1000 bytes. Its international symbol is kB.

In computer technologies, a kilobyte is specified as 1024 (210). This is because the binary system is widely used in file management systems.

For the 1024 (210) byte value, the unit determined by the International Electrotechnical Commission (IEC) in 1998 is Kibibyte.

Kilobyte

Base System of 10 (1000 bytes)

According to the International System of Units (SI), kilo prefix is specified as 1000 (103). Accordingly, 1 kilobyte is equal to 1000 bytes.

This value is the value defined by the International Electrotechnical Commission (IEC).

The IEC 80000-13 standard states that 8 bits equal 1 byte. (1B = 8 bits). Accordingly, 1 kB = 8000 bits. One thousand kilobytes (1000 kB) equals 1 megabyte (1 MB).

Base System of 2 (1024 bytes)

Traditionally, 1 kilobyte is used to express 1024 bytes (210 B). The concept of metric kilos is used here because 1024 is close to 1000 for convenience.

Today, this notation format is used in many places.
Example: Microsoft Windows.
