Since 1 Indian Rupee is equal to 1.60611331218 Nepalese Rupees, we could say that n Indian Rupees are equal to 1.60611331218 times n Nepalese Rupees. In other words, we could use the following formula:
Nepalese Rupees = Indian Rupees x 1.60611331218
For example, let's say that we want to convert 2 Indian Rupees to Nepalese Rupees. Then, we just replace Indian Rupees in the abovementioned formula with 2:
Nepalese Rupees = 2 x 1.60611331218
That is, 2 Indian Rupees are equal to 3.21222662436 Nepalese Rupees.
