The currency used in Thailand is the Thai baht, abbreviated as THB. The baht is divided into 100 satang and comes in both banknotes and coins. The baht has been the official currency since the late 19th century when it replaced the tical. The exchange rate can fluctuate due to various economic factors, including tourism, trade, and foreign investment. The baht is widely accepted throughout Thailand, and while it may not be as familiar to international travelers, many currency exchange offices and banks handle foreign currency exchange for convenience.
