Two currencies, one of them yours
Cambodia runs on US dollars. Prices are quoted in dollars, ATMs dispense dollars, hotels and tours bill in dollars, and you can complete an entire trip without handling riel deliberately.
Riel is the change. The exchange rate sits around 4,000 riel to the dollar and it is deliberately stable, so a 1,000-riel note is a quarter and a 2,000 is fifty cents. Buy something for $1.50 with a $2 note and you get 2,000 riel back. That is the whole system and it works smoothly once you stop being surprised by it.
There are no US coins in circulation. Anything under a dollar comes back in riel, which is the single thing to internalise.
⚠️ Torn, marked or heavily worn dollar notes are routinely refused - by shops, by hotels, sometimes by banks. This catches almost every visitor once. Bring clean notes, check what an ATM or a money changer hands you before you walk away, and do not accept a damaged note as change.
Small denominations matter. Tuk-tuks, temple drink sellers, market stalls and tips all want ones and fives. Break a fifty at a hotel or a supermarket early and keep a stock of singles.
