Answer

In Jain tapasya counting, 1 Upvas is generally considered equal to:

• 2 Chauvihar Ekasana
• 2 Chauvihar Ayambil
• 4 Nivi

Explanation

The common equivalence used in many Jain communities is:

• 1 Upvas = fasting for the full day
• 2 Ekasana = counted as 1 Upvas
• 2 Ayambil = counted as 1 Upvas
• 4 Nivi = counted as 1 Upvas

So if someone asks “1 Upvas equals how many Ayambil, Ekasana, or Nivi?” the simple answer is:

1 Upvas = 2 Ayambil = 2 Ekasana = 4 Nivi.

Takeaway

These are practical tapasya-counting conventions followed in many places. Exact counting may vary slightly by sangh or tradition, so for a specific vow or pachchakkhan, it is best to follow your guru or local sangh guidance.
