षष्टिवेतनस्याढकं कृत्वा हिरण्यानुरूपं भक्तं कुर्यात् ॥ कZ_०५.३.३४ ॥
ṣaṣṭi-vetanasya āḍhakaṃ kṛtvā hiraṇyānurūpaṃ bhaktaṃ kuryāt
Taking an āḍhaka (a grain measure) as the standard corresponding to a wage-rate of sixty, he should determine the ration allowance in proportion to the cash (hiraṇya) component.
It standardizes how rations are computed relative to cash wages, preventing ad hoc allotments and leakage in kind-disbursements.
A fixed conversion benchmark (āḍhaka tied to a wage-rate) to compute proportional rations.
