How many bytes are in 1 kilobyte (KB)?

One kilobyte (KB) is defined as 1,024 bytes. This measurement is based on the binary system, where data is processed in powers of two. In this system, a kilobyte is equivalent to 2 raised to the power of 10, which equals 1,024.

This concept is rooted in the way computers store and manage data, as they operate using binary digits (bits), where each byte consists of 8 bits.

Understanding this binary basis for measuring data is crucial in computing contexts, where knowing how data sizes scale—from bits to bytes to kilobytes and beyond—helps in tasks such as data storage management and network data transfer rates.
