Editing Hexadecimal (section)

===Other simple conversions===

Although [[Quaternary numeral system|quaternary]] (base 4) is little used, it can easily be converted to and from hexadecimal or binary. Each hexadecimal digit corresponds to a pair of quaternary digits, and each quaternary digit corresponds to a pair of binary digits. In the above example 2&nbsp;5&nbsp;C<sub>16</sub> = 02&nbsp;11&nbsp;30<sub>4</sub>.

The [[octal]] (base 8) system can also be converted with relative ease, although not quite as trivially as with bases 2 and 4. Each octal digit corresponds to three binary digits, rather than four. Therefore, we can convert between octal and hexadecimal via an intermediate conversion to binary followed by regrouping the binary digits in groups of either three or four.
