Or
24 (in countries that use "long scale" naming conventions)
Nonillion: 30 in short scale Or 54 in long scale

A quadrillion has 15 zeros, so there would be 15 zeros in a quadrillion miles.
30 * * * * * No. In the short scale it is 27. A nonillion has 30 zeros.
One quadrillion = 1,000,000,000,000,000There's 15 zeroes in one quadrillion.
The number five quadrillion will have approximately 15 zeros.
One nonillion is equal to 1 followed by 30 zeros. This is because the prefix "noni-" denotes a factor of 10^30 in the long scale numbering system. Therefore, there are 30 zeros in one nonillion.
