A duecentillion is a large numerical value in the short scale system, which is used primarily in the United States and modern English-speaking countries. It is equal to 10 raised to the power of 600, or 1 followed by 600 zeros. In the long scale system, which is used in some European countries, a duecentillion represents a different value, specifically 10 raised to the power of 1200. The term derives from the Latin word "ducenti," meaning "two hundred."
