What it does
Convert between bits, bytes, kilobytes, megabytes, gigabytes, terabytes, and petabytes. Toggle between decimal (1000-based: KB, MB, GB) and binary (1024-based: KiB, MiB, GiB) modes — decimal is what storage vendors advertise, binary is what operating systems report, and the difference gets big at higher scales.
Handy for disk-space planning, bandwidth estimates, and understanding why your 1 TB drive shows as 931 GB. See also number base converter for binary/hex math and unit converter for general unit work.
