centillion

Three-hundred-three zeros

Centillion is an enormous number, written as 1 followed by 303 zeros in American usage, or 1 followed by 600 zeros in British usage.

Like other vast numerical terms (quintillion, sextillion), it appears mainly in contexts emphasizing incomprehensibly large quantities: There are a centillion possible outcomes.

The word derives from Latin centum (hundred), marking it as the hundredth power in the naming system.
