Convert and format byte sizes in SI (kB) and IEC (KiB) units.
About this tool
Type a size such as 1.5 GB, 512 KiB or 2048 and see it in bytes, in decimal units and in binary units. A plain number is read as bytes.
Decimal units (kB, MB, GB) step by 1000, which is how drives and network speeds are usually labelled. Binary units (KiB, MiB, GiB) step by 1024, which is how memory and many operating systems count.
