    Arguments ('*' denotes required arguments):

    *   quantity => *str* (default: "1 mg")

        (No description)

    *   to_unit => *str*

        (No description)

    Returns an enveloped result (an array).

    First element ($status_code) is an integer containing HTTP-like status
    code (200 means OK, 4xx caller error, 5xx function error). Second
    element ($reason) is a string containing error message, or something
    like "OK" if status is 200. Third element ($payload) is the actual
    result, but usually not present when enveloped result is an error
    response ($status_code is not 2xx). Fourth element (%result_meta) is
    called result metadata and is optional, a hash that contains extra
    information, much like how HTTP response headers provide additional
    metadata.

    Return value: (any)

  convert_iron_unit

    *   How much of sodium chloride provides 1000 mg of elemental sodium?:

         convert_sodium_unit(quantity => "1000 mg-na-elem", to_unit => "mg-na-cl");

        Result:

         [200, "OK", 2544.52926208651, {}]

    If target unit is not specified, will show all known conversions.

    This function is not exported.

    Arguments ('*' denotes required arguments):

    *   quantity => *str* (default: "1 mg")

        (No description)

    *   to_unit => *str*

        (No description)

    Returns an enveloped result (an array).

    First element ($status_code) is an integer containing HTTP-like status
    code (200 means OK, 4xx caller error, 5xx function error). Second
    element ($reason) is a string containing error message, or something
    like "OK" if status is 200. Third element ($payload) is the actual
    result, but usually not present when enveloped result is an error
    response ($status_code is not 2xx). Fourth element (%result_meta) is
    called result metadata and is optional, a hash that contains extra
    information, much like how HTTP response headers provide additional
    metadata.

    Return value: (any)

  convert_zinc_unit
    Usage:

     convert_zinc_unit(%args) -> [$status_code, $reason, $payload, \%result_meta]

    Convert a zinc quantity from one unit to another.

CONTRIBUTING
    To contribute, you can send patches by email/via RT, or send pull
    requests on GitHub.

    Most of the time, you don't need to build the distribution yourself. You
    can simply modify the code, then test via:

     % prove -l

    If you want to build the distribution (e.g. to try to install it locally
    on your system), you can install Dist::Zilla,
    Dist::Zilla::PluginBundle::Author::PERLANCAR,
    Pod::Weaver::PluginBundle::Author::PERLANCAR, and sometimes one or two
    other Dist::Zilla- and/or Pod::Weaver plugins. Any additional steps
    required beyond that are considered a bug and can be reported to me.

BUGS
    Please report any bugs or feature requests on the bugtracker website

    When submitting a bug or request, please include a test-file or a patch
    to an existing test-file that illustrates the bug or desired feature.
