Decimal SI and binary IEC data storage units from individual bits through yotta-scale storage.
All factors come from the central conversion registry.
| Unit | Symbol | System | Definition |
|---|---|---|---|
| Bit | bit | Data | 1 bit = 1 bit |
| Kilobit | kbit | SI decimal | 1 kbit = 1000 bits |
| Nibble | nibble | Data | 1 nibble = 4 bits |
| Megabit | Mbit | SI decimal | 1 Mbit = 10⁶ bits |
| Gigabit | Gbit | SI decimal | 1 Gbit = 10⁹ bits |
| Terabit | Tbit | SI decimal | 1 Tbit = 10¹² bits |
| Petabit | Pbit | SI decimal | 1 Pbit = 10¹⁵ bits |
| Exabit | Ebit | SI decimal | 1 Ebit = 10¹⁸ bits |
| Zettabit | Zbit | SI decimal | 1 Zbit = 10²¹ bits |
| Yottabit | Ybit | SI decimal | 1 Ybit = 10²⁴ bits |
| Byte | B | Data | 1 byte = 8 bits |
| Kilobyte | KB | SI decimal | 1 KB = 1000 bytes |
| Megabyte | MB | SI decimal | 1 MB = 1000 KB |
| Gigabyte | GB | SI decimal | 1 GB = 1000 MB |
| Terabyte | TB | SI decimal | 1 TB = 1000 GB |
| Petabyte | PB | SI decimal | 1 PB = 1000 TB |
| Exabyte | EB | SI decimal | 1 EB = 1000 PB = 10¹⁸ bytes |
| Zettabyte | ZB | SI decimal | 1 ZB = 1000 EB = 10²¹ bytes |
| Yottabyte | YB | SI decimal | 1 YB = 1000 ZB = 10²⁴ bytes |
| Kibibyte | KiB | IEC binary | 1 KiB = 1024 bytes |
| Mebibyte | MiB | IEC binary | 1 MiB = 1024 KiB |
| Gibibyte | GiB | IEC binary | 1 GiB = 1024 MiB |
| Tebibyte | TiB | IEC binary | 1 TiB = 1024 GiB |
| Pebibyte | PiB | IEC binary | 1 PiB = 1024 TiB |
| Exbibyte | EiB | IEC binary | 1 EiB = 1024 PiB = 2⁶⁰ bytes |
| Zebibyte | ZiB | IEC binary | 1 ZiB = 1024 EiB = 2⁷⁰ bytes |
| Yobibyte | YiB | IEC binary | 1 YiB = 1024 ZiB = 2⁸⁰ bytes |
Data storage keeps decimal SI prefixes and binary IEC prefixes distinct. For example, 1 GB is 1,000,000,000 bytes while 1 GiB is 1,073,741,824 bytes.
The interactive calculator, reference table and indexed pair pages all read from the same conversion registry, so unit definitions and formulas stay synchronized.
Byte-size conversions use explicit decimal SI or binary IEC definitions. The decimal units KB, MB, GB and TB scale by powers of 1000. Binary units KiB, MiB, GiB and TiB scale by powers of 1024 and are kept separate in this converter.
One byte contains exactly 8 bits. For text decoding rather than storage-size arithmetic, use the bytes to string decoder and choose the text encoding.
