Centillion

One centillion is a number, which is equal to either 10³⁰³ or 10⁶⁰⁰, depending on the system used.

Short scale

In areas using the short scale such as Canada, the US, and the UK, a centillion is 10³⁰³. It is formed on a pattern starting with a million: a million (1,000,000) has three zeroes more than a thousand (1,000); a billion (1,000,000,000) has two groups of three zeroes more than a thousand, and so on. One centillion has one hundred groups of three zeroes more than one thousand.

• A centillion is a thousand times more than a novemnonagintillion.
• A centillion is a thousandth of an uncentillion.

A centillion in the short-scale system is equivalent to a quinquagintilliard, or a thousand quinquagintillion, in the long-scale system.

Long scale

In long scale usage, one centillion is 10⁶⁰⁰, which is equal to (10⁶)¹⁰⁰; that is, it is the number with a hundred times as many zeroes as a million.

• A centillion is a thousand times more than a novemnonagintilliard.
• A centillion is a thousandth of a centilliard.
• A centillion is a million times more than a novemnonagintillion.
• A centillion is a millionth of an uncentillion.

A centillion in the long scale is equivalent to a cennovemnonagintillion in the short scale.^[1]
