Measurements – multiple plural forms

In my language, we have different plural forms for measurements of 2-4 and 5+ units. I would like to be able to change servings and then adjust the measurements accordingly. Is there a way to achieve this?

Plus I’d like to ask about the variations array in the code. I noticed it can have different number of parameters but I am not sure how it works and if it would not be the solution to my problem.

'g' => array(
    'singular_abbr' => _x('g','Grams Abbreviation (Singular)','cooked'),
    'plural_abbr' => _x('g','Grams Abbreviation (Plural)','cooked'),
    'singular' => esc_html__('gram','cooked'),
    'plural' => esc_html__('grams','cooked'),
    'variations' => array( 'g', 'g.', 'gram', 'grams' ),
),

Thank you!
