How much is 1000 in USD?

Excuse me, I'm curious about the current exchange rate. Could you please tell me how much Vietnamese Dong ( ) 1000 would translate into United States Dollars (USD)? I'm trying to budget for a trip to Vietnam and would like to have a rough estimate of the value in my home currency. Additionally, I'd appreciate it if you could provide an approximation or a range, given that exchange rates can fluctuate. Thank you for your assistance in this matter.
