How much is 1$ US in Dubai?

Excuse me, could you please clarify for me the current exchange rate for converting 1 US dollar to the local currency in Dubai? I'm trying to make a financial transaction and need to ensure I have the accurate amount in the local currency. Is there a specific bank or exchange service you recommend for getting the best rate? Additionally, are there any fees or charges I should be aware of when making this conversion? Thank you for your assistance.
