Answer

In Jain cosmology, one lakh yojan means:

• 1 lakh = 100,000
• So, one lakh yojan = 100,000 yojan

Explanation

A yojan is an ancient unit of distance used in Jain scriptures and Indian traditions. In Jain cosmology, very large distances—such as the size of continents, oceans, heavens, hells, and lokākāśa—are often described in yojan.

So if a text says something is one lakh yojan, it simply means it measures 100,000 yojan.

Takeaway

One lakh yojan = 100,000 yojan in Jain measurement terminology.
