how many zeros are in one quintrillion?

Question

how many zeros are in one quintrillion?
can you think of a bigger number excluding infinity?

Answer 1

In America, a quintillion is 1 000 000 000 000 000 000 (1^18)

In Traditional British, a quintillion is 1 000 000 000 000 000 000 000 000 000 000 (1^30)

Answer 2

The accepted suffixes as far as I know:
million (6 0s)
billion (9)
trillion (12)
quadrillion (15)
quintillion (18) (no "r" there)
sextillion (21)
septillion (24)
octillion (27)
nonillion (30)
decillion (33)

It stands to reason that dodecillion (39) would exist, but I don't know the one in between that and decillion, and I've never seen anyone bother with it. Scientific notation is typically used at the higher numbers.

There is the "googol" - 100 zeros, and the "googol-plex", which is 10 to the googol power - entirely nonsensical. Those are just sort of made up numbers (you will note they don't have 0 groupings of three), although they certainly exist and have been thought of.

I had a physics professor speculate that the total number of subatomic particles in the universe was less than a googol. I don't know if he was exactly right, but at some point of course you must question the value of numbers beyond a certain point.

Answer 3

Billion > 9 zeros
Trillion >. 12 zeros
Quadrillion > 15 zeros
Quintillion > 18 zeros

Answer 4

I'm not sure if you meant quintillion... there is no 'quintrillion'

Here's the number of zeroes in the amounts up to 1 quintillion
million 6
billion 9
trillion 12
quadrillion 15
quintillion 18

But there are more
sextillion 21
septillion 24
octillion 27
nonillion 30
decillion 33
undecillion 36
duodecillion 39
tredecillion 42
quattuordecillion 45
quindecillion (quinquadecillion) 48
sexdecillion (sedecillion) 51
septendecillion 54
octodecillion 57
novemdecillion (novendecillion) 60
vigintillion 63
googol 100
centillion 303
googolplex 10^100

Answer 5

A googol is 1 followed by 100 zeros.
A googolplex is 1 followed by a googol zeros.
So a googolplex is the largest number. Until you add 1 to it.

There is no largest number, because you can keep adding 1 and getting a larger number.

Answer 6

1 quintrillion is 10 raised to the power of 18

Answer 7

18 zeros in quintillion.

Here are some bigger numbers

sextillion
septillion
octillion
nonillion
decillion

eventually, you get to google, which has 100 zeros, and then you get to google plex, which is a 1, followed by google zeros.

pretty cumbersome to write this way- look into scientific notation.

Answer 8

Depends where you're from. Some say 18, as they count thousand, million, billion, trillion... (going up by a factor of 1000 each time) others say 30, as they count thousand, million, thousand million, billion, thousand billion, trillion ... (again each number here is a thousand times as large as its predecessor)

As to larger numbers, many things spring to mind, like Avogadro's number for one, or myriads etc.

Answer 9

quintrillion is 10 raised to the power of 18

Answer 10

the term is QUINTILLION...

1 followed by 18 zeros
