How much is $100 Ethereum in dollars?

Could you please clarify for me, how much is $100 worth of Ethereum converted into US dollars? I'm trying to understand the current market value, but the exchange rates seem to be fluctuating quite frequently. Could you help me out with a rough estimate? I'm not expecting an exact figure, but just a ballpark amount would be helpful. Is there a way to quickly check the conversion rate online? Also, could you explain how the value of Ethereum typically fluctuates compared to other cryptocurrencies and traditional currencies? Thank you for your assistance.
