quintillions
Eighteen zeros follow
Quintillions is the plural of quintillion, a number represented by 1 followed by 18 zeros in American usage, or 30 zeros in British usage.
Like other large-number plurals, it often appears hyperbolically to mean an unfathomably large quantity: There are quintillions of grains of sand on Earth's beaches.
