In Jain cosmology, 1 sagaropama is an extremely large unit of time.

A commonly given traditional explanation is:

• 1 palyopama = a vast, almost unimaginable unit of time
• 1 sagaropama = 1 crore (10 million) palyopamas

So, a sagaropama is 10 million palyopamas.

It is used in Jain scriptures to express very long durations, especially in discussions of karma, celestial lifespans, and cosmic time. Exact numerical conversion in modern years is not practically fixed, because these are scriptural time units, not ordinary calendar units.

If you want, I can also explain the related Jain time units like avali, muhūrta, palyopama, and sagaropama in simple order.
