A yojana (Devanagari: à ¤¯à ¥Âà ¤Âà ¤¨; Khmer language: áÂÂáÂÂáÂÂáÂÂáÂÂ; ; ) is a measure of distance that was used in ancient India, Cambodia, Thailand and Myanmar. Some sources define the unit as the distance an army can march in a day. Various textual sources from ancient India define Yojana as ranging from 3.5 to 15 km.
Ashoka, in his Major Rock Edict No.13, gives a distance of 600 yojanas between the Maurya empire, and "where the Yona king named Antiyoga (is ruling)", identified as King Antiochus II Theos, whose capital was Babylon. A range of estimates, for the length of a yojana, based on the ~2,000 km from Baghdad to Kandahar, on the eastern border of the empire, to the ~4,000 km to the Capital at Patna, have been offered by historians.

In Hindu scriptures, ParamÃÂá¹Âu is the fundamental particle and smallest unit of length.
The length of the yojana varied over time and locale, its length has been estimated as:
