Is 400 Robux 5 dollars?

Could you please clarify the conversion rate between Robux, the virtual currency used in the Roblox platform, and US dollars? Specifically, I'm wondering if 400 Robux is equivalent to 5 dollars. It's important to note that the exchange rate between Robux and real-world currencies can vary, depending on market conditions and Roblox's policies. Could you elaborate on the current or typical conversion rate, and whether 400 Robux would typically equate to 5 dollars or a different amount? This information would help me better understand the value of Robux and its relationship to traditional currencies.
