What is Kilobyte?

The kilobyte is a unit of digital data equal to 1,000 bytes (one thousand bytes). Short text files, simple HTML pages, and plain-text emails typically measure just a few kilobytes. In the early history of computing, programs and games ran in kilobytes of memory, and the unit remains a symbol of efficient programming. Today, kilobytes are used for small configuration files, icons, and plain-text documents. This tool uses SI prefixes where 1 KB equals 1,000 bytes.

What is Byte?

The byte is the fundamental unit of digital data, consisting of 8 bits. One byte is enough to represent a single ASCII character such as a letter or digit. In UTF-8 encoding, a Japanese character typically requires 3 bytes. All larger data units (KB, MB, GB, TB) are built upon the byte. It serves as the basic addressable unit in computer memory and storage systems.
