FAQ
Supports decimal units like B, KB, MB, GB, TB, PB, and binary units like KiB, MiB, GiB, TiB. A total of 10 common storage units are available for quick conversion.
Decimal units (KB/MB/GB) use base 1000, commonly used by hard drive manufacturers and network transmission. Binary units (KiB/MiB/GiB) use base 1024, used by operating systems and memory. 1 GB = 1000 MB, while 1 GiB = 1024 MiB.
Drive manufacturers use decimal (base 1000) for labeling, while operating systems display in binary (base 1024). For example, a 1 TB drive shows as ~931 GiB in the system. This is normal, not a capacity shortage.
