The Śulvasūtras give the construction rules of the sacrificial altars, these alters are made in bricks in very complicated shape and size, in fact all the construction ware done with rope and pegs. The Śulva (rope) was used to solve propositions about the construction of various rectilinear figures; combination, transformation, and application of areas; menstruation of areas and volumes; squaring of the circle and vice versa and many others geometrical figures. That’s why the Śulvasūtras give the units of measurements. The units like aṅgulam, padam, prakramam, prādeśam and many others used in the Śulvasūtras. The terms reveal that these were coined from body measures being commonly used in daily life, and became quite popular in social life. Although they are derived from the basic unit “Puruṣa”, [size of the Yajamāna] standardization measures are also taken. An aṅgulam is a standard unit of measurement; it is equal to fourteen grains of the aṇu and it is equal to thirty-four tilam (sesame) grains put together with their broad sides.
