c15.s1.t5.6

³ Since 24 *aṅgulas*=1 *hasta* and the diameter of the moon was reckoned as 15 *aṅgulas*, and its mean diameter as 32 minutes (SS. IV, 1) we have approximately 1 *aṅgula*=2' 8" and 1 *hasta*=51' 12" roughly; but possibly 1 *aṅgula* was meant to measure 2 minutes. Also 27 *nakshatras* occupy 360° and one therefore occupies 13⅓ degrees.
