Byte quick reference
| Byte | Bit | Gigabyte | Gibibyte |
|---|---|---|---|
| 1 B | = 8 bit | = 1e-9 GB | ≈ 9.313225746e-10 GiB |
| 10 B | = 80 bit | = 1e-8 GB | ≈ 9.313225746e-9 GiB |
| 100 B | = 800 bit | = 1e-7 GB | ≈ 9.313225746e-8 GiB |
| 1000 B | = 8000 bit | = 0.000001 GB | ≈ 9.313225746e-7 GiB |
Where the byte fits
The next smaller data storage unit is the nibble (nibble). 1 B = 2 nibble, and 1 nibble = 0.5 B.
The next larger data storage unit is the kilobit (kbit). 1 B = 0.008 kbit, and 1 kbit = 125 B.
