We need to apply two conversion factors to convert one crore Rupees into US Dollars - we need to convert 'crore' into US numerical system and we need to convert Rupees into Dollars. Crore is a unit in Indian numerical system which is equivalent to 10 million. So one crore Rupees is same as 10 million Rupees. This part is fixed and doesn't change with time. Next, we need to convert Rupees into Dollars - and for that we need the currency exchange rate between Rupee and Dollar. That varies over time but right now is hovering around ~60 Rupees = 1 US Dollar. So overall, 1 crore Rupees = 10 million Rupees = (10 Million / 60) US Dollars = 160, 000 US Dollars.
