Shankh's Position Between Padma and Mahashankh
The direct answer: exactly 17 zeros. The traditional Indian scale adds two zeros at each step, so shankh has two more zeros than padma (15) and two fewer than mahashankh (19).

|---|---|---|
| Padma | 15 | 1 quadrillion |
| Shankh | 17 | 100 quadrillion |
| Mahashankh | 19 | 10 quintillion |
