Cambodian Cash is the official currency of Cambodia and is divided into two denominations: Riel (5 letters) and Riel (4 letters). The Riel is the primary unit of currency, with 100 Riel equaling one Riel. The Riel is used for everyday transactions, while the Riel is used for larger purchases. The Cambodian Riel is not widely accepted outside of Cambodia, so it is important to exchange it for a more widely accepted currency before traveling.
