There are two correct answers to this question for each:
Quadrillion:
15 (in the USA and in any countries that use "short scale" naming conventions)
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.
The number five quadrillion will have approximately 15 zeros.
One quadrillion = 1,000,000,000,000,000There's 15 zeroes in one quadrillion.
nonillion
A nonillion is equal to 1 followed by 30 zeros. This is because nonillion is the number 1 with 30 groups of three zeros after it. Each group of three zeros represents a power of 10 (thousand, million, billion, etc.), so in total, a nonillion has 30 zeros.
A quadrillion has 15 zeros, so there would be 15 zeros in a quadrillion miles.
31 total zeros 10,000,000,000,000,000,000,000,000,000,000
30 * * * * * No. In the short scale it is 27. A nonillion has 30 zeros.
This number is Nonillion and it has 30 zeros in it. That's a lot!
There are 15 zeros in a quadrillion. 1,000,000,000,000,000

Here is a quick list of numbers and how many 0s they have: Ten: 10 (1 zero) Hundred: 100 (2 zeros) Thousand: 1000 (3 zeros) Ten thousand 10,000 (4 zeros) Hundred thousand 100,000 (5 zeros) Million 1,000,000 (6 zeros) Billion 1,000,000,000 (9 zeros) Trillion 1,000,000,000,000 (12 zeros) Quadrillion 1,000,000,000,000,000 (15 zeros) Quintillion 1,000,000,000,000,000,000 (18 zeros) Sextillion 1,000,000,000,000,000,000,000 (21 zeros) Septillion 1,000,000,000,000,000,000,000,000 (24 zeros) Octillion 1,000,000,000,000,000,000,000,000,000 (27 zeros) Nonillion 1,000,000,000,000,000,000,000,000,000,000 (30 zeros) Decillion 1,000,000,000,000,000,000,000,000,000,000,000 (33 zeros)
Nonillion
The number five quadrillion will have approximately 15 zeros.
One quadrillion = 1,000,000,000,000,000There's 15 zeroes in one quadrillion.
