Can you convert WETH to USD?

Could you please explain to me how I can convert WETH to USD? I'm a bit new to the cryptocurrency world and I'm trying to understand the process of converting Wrapped Ether into US dollars. Is there a specific platform or exchange that I should be using for this conversion? Also, are there any fees involved in the conversion process? And how long does it typically take to complete the conversion? Your insights would be greatly appreciated.
