Koṭi (俱胝; pronounced [ju-]zhi: the name of a numerical reckoning method in the country of India. The *Avataṃsaka-sūtra*, in the chapter on asaṃkhyeyas [“Incalculable”], states: “One hundred thousand makes one lakṣa; in this country [China], this is counted as one yi (億). One hundred lakṣa make one koṭi.” Among the three grades of reckoning methods for a koṭi, this is the name of the middle reckoning).
