Units of Information
Amount of information is a non-SI base dimension. The unit of amount of information is the bit.
Units of information take IEC prefixes, not SI prefixes. Thus, 1024 bytes is a kibibyte, not a kilobyte.
Maple knows the units of information listed in the following table.
nibbles nybble nybbles
An asterisk ( * ) indicates the default context, an at sign (@) indicates an abbreviation, and under the prefixes column, SI indicates that the unit takes all SI prefixes, IEC indicates that the unit takes IEC prefixes, and SI+ and SI- indicate that the unit takes only positive and negative SI prefixes, respectively. Refer to a unit in the Units package by indexing the name or symbol with the context, for example, bit[information] or bps[information]; or, if the context is indicated as the default, by using only the unit name or symbol, for example, bit or bps.
The units of information are defined as follows.
A crumb is defined as 2 bits.
A nibble is defined as 4 bits.
A byte is defined as 8 bits.
A nickle is defined as 10 bits.
A word is defined as 16 bits.
A double word is defined as 32 bits.
A gawble is defined as 48 bits.
A block is defined as 4096 bits.
A bit_per_second is defined as a bit per second. (This is a unit with dimension amount_of_informationtime.)
