How much is a crore in dollars?

Could you please elaborate on the conversion rate between a crore and dollars? I'm particularly interested in understanding how much a crore translates to in US dollars. It's quite a large unit of currency, and I'm trying to grasp its equivalent value in a more familiar currency. Additionally, does this conversion rate fluctuate based on exchange rates, or is it a fixed amount? Clarifying this point would be helpful in my understanding. Thank you for your assistance in explaining this conversion.
