    To work out how much information (number of combinations) a given length number (n digits) in number base-m (ie. 2 for binary, 10 for decimal, 16 for hexidecimal) it is mn.<br />
    <br />
    1 hex digit can store 161 = 16 combinations or ‘states’, which is the same as 4 binary digits (24 = 16).<br />
    <br />
    <br />
    Some common conversions:<br />
    <br />
    1 octal = 3 binary<br />
    <br />
    1 hex = 4 binary<br />
    <br />
    1 base-64 = 8 binary
