Binary unit conversion relies on powers of two, unlike the decimal system that uses powers of ten. Because computers store data in bits, larger units such as bytes, kibibytes (KiB), mebibytes (MiB), and gibibytes (GiB) are defined as exact multiples of 2 (8, 1024, 1 048 576, 1 073 741 824 bits respectively).
To convert between any two binary units you first express the original quantity in its base unit – bits – then scale it to the target unit. This two‑step process guarantees precision, especially when mixing decimal‑prefixed units (KB, MB) with binary‑prefixed ones (KiB, MiB).
For example, converting 2 MiB to kilobytes (KB) involves: 2 MiB → bits (2 × 1 048 576 × 8) → kilobytes (÷ 8 000). The result is 2 MiB = 2 097 152 KB, illustrating the importance of using the correct binary factor.
