The degrees of the ascendant (lagna) and the life-span are to be tripled and then divided by the directions; the resulting quotient gives the total measure.

Vedāṅga Jyotiṣa—procedural arithmetic using lagna degrees, multiplication, division, quotient and remainder to derive directional portions (dik-bhāga) and related measures.
