A quintillion is a number written as either:
- a 1 followed by 18 zeros (10 to the 18th power, as used in the American system of numeration)
or
- a 1 followed by 30 zeros (10 to the 30th power, as used in the British/French system of numeration)
In the American system of numeration (sometimes called the "short scale"), this number is equal to 1,000 quadrillion, or a billion billion.
