How much is HKU USD?

Excuse me, could you please clarify what you mean by "HKU USD"? If you're referring to a specific cryptocurrency or financial instrument associated with the University of Hong Kong (HKU) and the US Dollar (USD), I'm not immediately familiar with such a direct connection. However, it's possible you're asking about the exchange rate between Hong Kong Dollars (HKD) and USD, or perhaps about a cryptocurrency that might have some relation to HKU but is primarily traded in or against USD. If you're looking for the exchange rate between HKD and USD, it fluctuates daily and can be easily found on various financial websites, mobile apps, or through your bank or financial institution. If you're inquiring about a specific cryptocurrency, it would be helpful to know the exact name or ticker symbol of that cryptocurrency to provide a more accurate response. Could you please elaborate or clarify your question?
