     * **Basic units (UNIT)**
     * * `bit`   bit
     * * `By`    byte
     * * `s`     second
     * * `min`   minute
     * * `h`     hour
     * * `d`     day
     * **Prefixes (PREFIX)**
     * * `k`     kilo    (10**3)
     * * `M`     mega    (10**6)
     * * `G`     giga    (10**9)
     * * `T`     tera    (10**12)
     * * `P`     peta    (10**15)
     * * `E`     exa     (10**18)
     * * `Z`     zetta   (10**21)
     * * `Y`     yotta   (10**24)
     * * `m`     milli   (10**-3)
     * * `u`     micro   (10**-6)
     * * `n`     nano    (10**-9)
     * * `p`     pico    (10**-12)
     * * `f`     femto   (10**-15)
     * * `a`     atto    (10**-18)
     * * `z`     zepto   (10**-21)
     * * `y`     yocto   (10**-24)
     * * `Ki`    kibi    (2**10)
     * * `Mi`    mebi    (2**20)
     * * `Gi`    gibi    (2**30)
     * * `Ti`    tebi    (2**40)
     * **Grammar**
     * The grammar also includes these connectors:
     * * `/`    division (as an infix operator, e.g. `1/s`).
     * * `.`    multiplication (as an infix operator, e.g. `GBy.d`)
     * The grammar for a unit is as follows:
     *     Expression = Component { "." Component } { "/" Component } ;
     *     Component = ( [ PREFIX ] UNIT | "%" ) [ Annotation ]
     *               | Annotation
     *               | "1"
     *               ;
     *     Annotation = "{" NAME "}" ;
     * Notes:
     * * `Annotation` is just a comment if it follows a `UNIT` and is
     *    equivalent to `1` if it is used alone. For examples,
     *    `{requests}/s == 1/s`, `By{transmitted}/s == By/s`.
     * * `NAME` is a sequence of non-blank printable ASCII characters not
     *    containing '{' or '}'.
     * * `1` represents dimensionless value 1, such as in `1/s`.
     * * `%` represents dimensionless value 1/100, and annotates values giving
     *    a percentage.
