ProfessorM,
Yojan used to be the distance of four villages. I have seen it described in one dictionary as 4 miles, though IQ describes it as 8 miles.
When I grew up we used miles but around the time I moved to USA, India switched to metric system. (I am still not good with metric system, as US won't switch)
In ancient times they used Yojan. (Masculine usage)
I knew that word but I have never used it in a sentence.
Yojana is arrangement, planned activity (Feminine)
Yojak would be the doer of Yojana or planner.
They are all derived from Sanskrit.
