Basic use
Enter a value followed by a symbol (e.g. 15 Mb or 47 GiB) to see its equivalents in bits and bytes in the SI and IEC systems. Autocomplete suggests valid symbols as you type.
Bits and bytes
Tell apart b (bit, lowercase) and B (byte, uppercase): 1 B = 8 b. The Common section shows the total in bits and in bytes.
SI vs IEC
The SI prefixes (kB, MB, GB...) use powers of 1000; the IEC prefixes (KiB, MiB, GiB...) use powers of 1024 per the IEC 80000-13 standard. So 1 kB = 1000 bytes but 1 KiB = 1024 bytes.
