Hiuen Tsang (c.650 A.D) in his historical account on India, has recorded that there were two *krośas* in India, an old one of 1000 *daṇḍas* and new one of 2000 *daṇḍas* reckoning in his time. Since 1 *yojana* = 4 *krośas*. This statement of Hiuen Tsang also corroborates that 1 *yojana* = 4000 *daṇḍas* (old measure) and 8000 *daṇḍas* (new measure) and the historical situation prevalent in his time. Āl- Bīrūni (c.1030 A.O.) studied astronomical data of the Indians and related *yojana* with *farsakh* and yard without any definition (Mainkar, 1975). Vogt (1903), Fleet (1906, 1912), Shamasastry (1913) tried to establish correlation with chinese *li* and units of other countries which have not also of much correlation.
