What is a quadrilian?

Answer 1

A quadrillion is a numerical value represented by 10^15, or 1,000,000,000,000,000. In the short scale used in the United States and most English-speaking countries, it is the equivalent of a thousand trillion. In the long scale, used in some European countries, a quadrillion refers to a million billion. The term is often used in contexts involving large quantities, such as in finance or data measurement.
