Amount of information is a non-SI base dimension. The unit of amount of information is the bit.

Units of information take IECprefixes , not SI prefixes. Thus, $1024$bytes is a kibibyte, not a kilobyte.

Maple knows the units of information listed in the following table.

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 $\frac{\mathrm{amount\_of\_information}}{\mathrm{time}}$.)
