How much is 1 dollar in Fortnite?

Excuse me, I'm a bit confused about the concept of converting traditional currencies into the virtual realm of Fortnite. Could you please clarify for me how much would one US dollar equate to in the game's currency system? I understand that Fortnite utilizes its own unique form of currency, and I'm seeking a straightforward conversion rate or explanation of the process to understand the value proposition better. Thank you in advance for your assistance.
