Denominations Above One Million
Most people know 1,000 is called a thousand, and 1,000,000
is called a million, but what is a quadrillion? Or a
sextillion? I have compiled this list for that
purpose.
There is not a standard naming scheme for numbers over a
million, and different countries call numbers different
things. There are two common naming conventions, most
countries use one or the other. They are the American, and the
British systems.
The American system is based on the old French system,
though the French recently switched to the British system. The
German system is exactly the same as the British
system.
The list is a bit difficult to read, sorry, I couldn't
write out the numbers, since a number with 600 zeros after it
would take up quite a bit of room.

There are other names of numbers that are not part of any standard
number system.

(too many to write down) |

Though generally speaking, a googol is just a term that means "A very big number" and a googolplex is just a term that means "An unimaginably large number."
