How much is 20000000 million naira in dollars?

I'm curious about the exchange rate between Nigerian naira and US dollars. Could you please tell me how much 200,000,000 million naira would be in dollars? I'm aware that exchange rates can fluctuate, but I'm just looking for a general estimate at this point. It's for a financial planning project I'm working on, and having an accurate conversion is crucial. Thank you for your assistance in clarifying this matter for me.
