Answer

In common Jain practice, 1 Upvas is often considered equal to 20 Navkarvali / Navkar Mala pakki.

Explanation

This is a practical devotional counting tradition, not a universal scriptural measurement. In some families, sanghs, or traditions, the count may vary slightly.

So if your local guru, sadharmik group, or family follows a specific niyam, you should follow that tradition.

Takeaway

Generally: 1 Upvas = 20 Navkar Mala pakki in many Jain counting practices.
