FAQ — Byte Converter Free Online Tool

Why does 1 KB = 1024 B, not 1000 B?

Computers use binary, so 1 KB = 2^10 = 1024 bytes. This is the standard in most operating systems and programming languages. Some contexts (hard drive manufacturing) use decimal (1 KB = 1000 B).

What is the difference between MB and MiB?

MB (megabyte) = 1000^2 bytes (decimal). MiB (mebibyte) = 1024^2 bytes (binary). This tool uses the binary standard (1024), which is most common in software.
