How much is 1 dollar in zen?

Excuse me, could you please clarify for me how much one US dollar is equivalent to in terms of Zen, the cryptocurrency? I'm a bit confused about the current exchange rate between the two and I'm hoping to get a clear understanding of how to convert my dollars into Zen. Is there a specific platform or tool that you recommend for checking the most up-to-date conversion rates? Thank you in advance for your help.
