The bit (a portmanteau of binary digit) is a basic unit of information used in computing and digital communications.
| Name of unit | Symbol | Definition | Relation to SI units | Unit System |
|---|---|---|---|---|
| bit | b | = 1 bit | = 1 bit | Metric system SI |
| bits | nibbles | bits | nibbles |
|---|---|---|---|
| 1 | = 0.25 | 6 | = 1.5 |
| 2 | = 0.5 | 7 | = 1.75 |
| 3 | = 0.75 | 8 | = 2 |
| 4 | = 1 | 9 | = 2.25 |
| 5 | = 1.25 | 10 | = 2.5 |
In computing, a nibble (often nybble or nyble to match the spelling of byte) is a four-bit aggregation, or half an octet.
| Name of unit | Symbol | Definition | Relation to SI units | Unit System |

| nibble | = 22 bit | = 22 bit | Metric system SI |
