Skt. Krośa, a unit of distance. In Hindi it is known as kos (कोस), also spelled coss, koss, kosh, krosh, and krosha. This is from the Sanskrit क्रोश krośa, which means "to call", as the unit was supposed to represent the distance at which another human could be heard. It is an ancient Indian subcontinental standard unit of distance since at least 4 BCE. A kos is about 200 meters or 0.125 miles. Another conversion is based on the Mughal emperor Akbar who standardized the unit to 5000 guz in the Ain-i-Akbari. The British in India standardized Akbar's guz to 33 inches, making the kos approx. 4191 meters. Another conversion suggested a koss to be approximately two English miles. [Erick Tsiknopoulos]
