The currency of Cambodia is the Cambodian riel, abbreviated as KHR. However, the US dollar is also widely used and accepted in the country for transactions, making it quite common for visitors to use dollars for shopping and services. The riel is often used for small purchases or by locals in day-to-day transactions. The exchange rate fluctuates, but as of October 2023, one US dollar is roughly equivalent to around 4,000 riels. Understanding the use of both currencies can be helpful for travelers to Cambodia to navigate the local market effectively.
