How Many Zeros in a Nonillion?
The Short Answer a nonillion has 30 zeros in the U.S. numbering system.
It's written as: 1,000,000,000,000,000,000,000,000,000,000
Scientific notation: 10^30
What Is a Nonillion?
"Non-" means nine, and a nonillion is the ninth value in the “illion” naming series:
- Million – 106
- Billion – 109
- Trillion – 1012
- ... up to Nonillion – 1030
It’s almost exclusively theoretical, useful in deep math, cosmology, or computational estimation.
