quintillion
Beyond a quadrillion
A quintillion is the number 1 followed by 18 zeros (1,000,000,000,000,000,000) in American usage, or 1 followed by 30 zeros in British usage.
Like other large number words, it appears mainly in scientific or astronomical contexts: The sun releases quintillions of joules of energy per second.
In casual speech, quintillion often just means an impossibly large quantity.
