Well, there's two ways to interpret that question:
- How much is the Chinese Dollar worth compared to the US Dollar
The current exchange rate has 1 Chinese Yuan (it's not a Dollar currency) worth approximately 14 US cents, or 1 US Dollar = 7.2 Chinese Yuan You can check exchange rates at http://www.xe.com - the exchange rates change slightly every day.
- Can I use Chinese Currency in the USA?
To which the answer in most instances is no - if you tried paying for items in Chinese Yuan at Wallmart, I'd say they wouldn't accept the money.
