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 Kibibyte?

The kibibyte is an IEC binary prefix unit equal to exactly 1,024 bytes (2 to the 10th power). It was introduced in 1998 to resolve the ambiguity of "kilobyte," which historically referred to both 1,000 and 1,024 bytes depending on context. In systems programming, memory page sizes (commonly 4 KiB) and buffer sizes are specified in kibibytes. The distinction matters most in large-scale computing where the cumulative difference between powers of ten and powers of two becomes significant.
