quadrillion
Beyond a trillion
Quadrillion is a thousand trillion—a one followed by fifteen zeros (1,000,000,000,000,000).
Like other massive numbers, it appears mainly in scientific contexts: quadrillions of bacteria, a quadrillion calculations per second.
In casual use, quadrillion often just means an unimaginably large quantity: I've told you a quadrillion times.
