In Jain and ancient Indian measurement, a yojan is a unit of distance used to describe long travel between towns or places.

• Typical range: about 8 to 12 miles (roughly 12 to 19 kilometers).
• Because old texts didn’t fix a single exact value, some traditions give slightly different numbers within that range.
• Use: you’ll see yojan used in scriptures and navigational figures to indicate how far apart places are, often describing journeys or the spread of places in a region.

If you’d like, I can give a few example conversions (e.g., how many kilometers a certain number of yojanas would be) or point to where yojan appears in specific Jain verses.
