is a 1-d unit in this direction. It has a value of 500 or 1000 times larger than utsedha yojana or it is equivalent to 4000 or 8000 miles (1 yojana-8 miles). Other different values based on various values of utsedha yojana are given in Table 6 varying between 664015090 km. These are measurable units.

With reference to the dimensions of the Universe, there is one more unit named as rajju. Cannonically, it seems difficult to evaluate the current value for it, as its calculations involve innumerable number. Despite this, L. C. Jain and G. R. Jain have calculated the value of rajju unit to be between 1018-1021 kms. Jagasreni is still a larger unit which is equal to 7 rajjus or between 1019-1022 kms. These larger units are just akin to the current units of light-year which has a value of app. 1012 km. This suggests that the larger units of length of the Jainas are sufficiently larger. These are also included in Table 7.
