Answer

If you mean 1 Deva year = 360 human years, then 10,000 Deva years = 3,600,000 human years on Earth.

Explanation

The usual traditional conversion used is:

• 1 Deva year = 360 Earth years
• 10,000 Deva years = 10,000 × 360
• = 3,600,000 Earth years

Spiritual Understanding

Jain cosmology shows that time in different realms is not experienced the same way. This reminds us that worldly time is relative, while the soul’s journey is measured by karma and spiritual progress, not just years.

Takeaway

So, 10,000 Dev Lok years is about 36 lakh Earth years.
