उदारकस्तुल्यः यवा गोधूमाश्च क्षुण्णाः तिला यवा मुद्गमाषाश्च घृष्टाः ॥ कZ_०२.१५.२७ ॥
udārakas-tulyaḥ yavā godhūmāś ca kṣuṇṇāḥ tilā yavā mudga-māṣāś ca ghṛṣṭāḥ
Crushed barley and wheat are to be treated as equivalent to udāraka; likewise, rubbed (de-husked/cleaned) sesame and barley, and rubbed mung and black gram, are to be treated as equivalent (for accounting and issue).
It creates a single accounting category so storekeepers can issue rations and record consumption using standardized equivalences despite different processing states.
Because processing changes usable yield and weight; the state needs explicit equivalence rules to prevent pilferage and disputes in measurement.
