In Jain cosmology, 1 Yojana is a long distance unit. The standard traditional equivalence most often cited is:

• 1 Yojana ≈ 8 miles
• ≈ 42,000 feet (about 12.8 kilometers)

So, 1 Yojana is roughly forty-two thousand feet. Note that exact values can vary slightly between different Jain traditions and texts, but the above is the commonly used approximation.
