| Common Name (decimal system) | Decimal Value (bytes) | Binary System Equivalent | Binary Value (bytes) | Equal To (binary) | Description |
|---|---|---|---|---|---|
| Bit | 1/8 | Bit | 1/8 | 1/8 Byte | Every individual binary digit (0 and 1) |
| Nibble | 1/2 | Nibble | 1/2 | 4 Bits or 1/2 Byte | Combination of four bits of binary digits or half of an octet – can be represented by a single hexadecimal digit |
| Byte | 1 | Byte | 1 | 8 Bits | A unit of data that is eight binary digits long, and can be represented using a letter, number, or character (e.g. "h", "7", or "$") |
| Kilobyte (KB) | 1,000 (103) | Kibibyte (KiB) | 1,024 (210) | 1,024 Bytes | Often used to measure the size of small files |
| Megabyte (MB) | 1,000,000 (106) | Mebibyte (MiB) | 1,048,576 (220) | 1,024 KB | Often used to measure the size of large files |
| Gigabyte (GB) | 1,000,000,000 (109) | Gibibyte (GiB) | 1,073,741,824 (230) | 1,024 MB | Often used to measure the storage of a device's capacity |
| Terabyte (TB) | 1,000,000,000,000 (1012) | Tebibyte (TiB) | 1,099,511,627,776 (240) | 1,024 GB | Used to measure the storage of a very large device's capacity, such as a server or workstation with multiple hard drives |
| Petabyte (PB) | 1,000,000,000,000,000 (1015) | Pebibyte (PiB) | 1,125,899,906,842,624 (250) | 1,024 TB | Could be used to measure the total data stored in large networks or server farms |
| Exabyte (EB) | 1,000,000,000,000,000,000 (1018) | Exbibyte (EiB) | 1,152,921,504,606,846,976 (260) | 1,024 PB | So large that it isn't currently used to really measure any server farms or storage devices, but it could be used to measure the amount of data over multiple storage networks or the amount of data transferred over the internet for a certain amount of time |
| Zettabyte (ZB) | 1,000,000,000,000,000,000,000 (1021) | Zebibyte (ZiB) | 1,180,591,620,717,411,303,424 (270) | 1,024 EB | Used to measure large amounts of data throughout the world |
| Yottabyte (YB) | 1,000,000,000,000,000,000,000,000 (1024) | Yobibyte (YiB) | 1,208,925,819,614,629,174,706,176 (280) | 1,024 ZB | Currently no practical use of such a large measurement because all data in the world is made up of just a few zettabytes |
