Answer

In Jain tradition, 1 yojan is commonly understood as approximately 4 kos, and is often estimated around 8–9 miles or 13–14.5 kilometers.

So:

• 1,200,000 yojan ≈ 9,600,000 to 10,800,000 miles
• 1,200,000 yojan ≈ 15,600,000 to 17,400,000 kilometers

Explanation

Because ancient Jain cosmology uses traditional distance units, modern conversion is approximate. Different traditions and scholars may give slightly different values for one yojan.

Using the common estimate:

• If 1 yojan ≈ 8 miles: 1,200,000 × 8 = 9,600,000 miles
• If 1 yojan ≈ 9 miles: 1,200,000 × 9 = 10,800,000 miles

Takeaway

1,200,000 yojan is roughly 10 million miles, depending on the conversion used.
